The 240mm radiator, however, is thicker and has tighter packed fins. This topic is locked from further discussion. The full test methodology is available in the GamersNexus reviewand was used throughout this cooling optimization test. :] level 1. Reviews: 0. I'm new to water cooling and just bought a corsair aio. A really interessting test considering that top intake is the best cooling option in this case. Sorry if this sub is just meant for custom liquid cooling, this is the best place I thought I could ask. Who knows about the VRM/Mosfet though. Anyone is welcome to seek the input of our helpful community as they piece together their desktop. Nice info. (intake) or b) exhausting air from "inside" the case through the radiator and out the top of my case (exhaust) This is the place to ask! Note 2: At 4.2Ghz, the processor does not warm the radiator enough to heavily affect GPU temperatures when the radiator is mounted at the front. Wise Guy. 5. Someone who overclocks very high, needs the coolest CPU temperatures, and doesn't mind the noise too much will benefit from having the radiator intake from the top. This should provide more consistent results than using BOINC's Rosetta@Home. :]. i prefer more intake than exhaust, but thats because my silverstone raven 2 works better that way. Zarter. The other custom XT6 exhaust was around $500 including the header and a cat converter I supplied. However at 4.6Ghz, the radiator and the air coming out of it is very warm and can heavily affect internal case temperatures. Usually it's recommended to have your aio mounted in the front in this situation as it significantly improves cpu temps while only worsening gpu temps a bit. No airflow conflict with rear exhaust fan. The Revision 2 model I have has removable power cables, which addresses the problem the H220/Glacer had with fraying or damaged power cables that rendered the pump useless. We’ll recap some of the most critical aspects here: Thermal tests were conducted using an Intel Core i7-6700K Skylake CPU and Z170 mITX platform, parts listed below. Joined: 17 Dec 2009 Posts: 1,881. Should I be: a) pulling "fresh" air in from the top of my case through the radiator. Very muted fan noise, very faint pump noise. last updated – posted 2018-May-6, 3:58 pm AEST posted 2018-May-6, 3:58 pm AEST User #207427 1705 posts. And I LOST hp and torque (around 10hp/10lb-ft, 2.5") with that setup because the diameter was too wide (It was my choosing). Basically one of those things where it's just personal preference. However, depending on the fan you use, you may incur a heavy noise penalty (the Noiseblocker Eloop is a great example of this). However, you may need to invest in some air filters for the rear fan. As suggested above, I would certainly set the H115i fans to exhaust heat out the top. Hose and fan cables may not be long enough. 0. In the midst of my aircooler and watercooling testing, I wanted to see how much of an effect radiator position had with airflow and temperature. last updated – posted 2008-Jun-26, 4:46 pm AEST posted 2008-Jun-26, 4:46 pm AEST User #183846 445 posts. The front mount lies in the middle in terms of cooling for the radiator. 3 3. All-in-One CPU-WaKü Radiator als intake oder exhaust. Top radiator is 360mm long. Press J to jump to the feed. A bottom intake fan is recommended. Participant reference: whrl.pl/ReTrLh. Hi, not sure what is best, decided on getting the Corsair 600C … The radiator … The dust thing can't be overstated. As the water temperature inside the loop moves fast enough, the the water temperature will be the same throughout the loop and there therefore no trade of. The Glacer 240L is essentially a Swiftech H220 with Cooler Master Blade Master 2300 RPM fans, a faster pump, and no PWM splitter. Forum Posts. Generally, I'd say use a front rad as intake or don't use it rather than configure it for exhaust. So i have these 2 options ( blue rectangles are intake fans, red are exhaust ) : So here goes! I have a Corsair H110 with stock fans and I run push intake with the radiator on top, exhaust out the rear 2 fans intake from the front. /r/buildapc is a community-driven subreddit dedicated to custom PC assembly. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. The manufacturer recommendation of having the radiator intake from the top is a good recommendation. Hallo, ich werde am Wochenende in das Lian Li PC-O11 Air 3x 30mm 360 Radiatoren einbauen. Rear exhaust fan steals air from radiator. Archive View Return to standard view. 0. It's recommended that you remove or reverse the rear exhaust fan to provide fresh cooling to the radiator. I went with dual intakes and did some testing in my Define R6. If the radiator fans are exhausting, they would be pulling hot air from the gpu through the radiator. OR having a few more intake than exhaust fans can be helpful. Posted by 5 days ago. Filtered, fresh air from the front (though slightly restricted). Top mount radiators - Intake or Exhaust fan setup? Show only OP | 11 Aug 2019 at 21:47 #1. It does the best for noise too. Glad to see my setup is optimal for my needs (and seeing as my hearing sucks noise isnt much of an issue for me), Doing God's work, /u/Pianowned. Forum Regular reference: whrl.pl/RbyBDd. The GPU (GTX 980 Ti) was using an NVIDIA reference design cooler (blower fan), which will yield … You’d be fine placing your rad on top. This means you will have 3-4 intake and 3 exhaust giving you relatively balanced airflow and overall the best thermals you can realistically get. Intakes fresh air from the top, runs coolest. März 2020; G. GushO Cadet 2nd Year. posted 2018-May-5, 5:51 pm AEST ref: whrl.pl/Re87Nq. I see every kind of setup on Reddit, but nothing seems to confirm that one is better than another. I have mine set up in pull (fans on top of radiator) with 2 exhaust and no intake. I was thinking about trying something similar with the h220x I pre ordered... New comments cannot be posted and votes cannot be cast. Using radiator as intake on the other hand hardly effects GPU temps in game. However I'll be honest I haven't tested this inverted setup, which is why I said theoretically. Corsair recommends that you use it as an intake but then I'll have 3 120mm front intakes, 2 120mm top intakes and only one 140mm back exhaust. The commonly done configuration of having the radiator exhaust from the top doesn't bode too well for radiator cooling (but certainly helps GPU cooling a bit). NZXT Grid w/ Fractal Design 3-speed fan controller, Gigabyte EasyTune, Unigine Valley 1.0, Extreme HD preset, Windowed 1920 x 1080, 8xMSAA. Radiator uses warm air. Discussion in 'Overclocking & Cooling' started by Jonnybmac, 11 Aug 2019. Also, I have switched out the Noiseblockers in favor of the Noctua IndustrialPPC NF-F12 since the Noiseblockers exhibited very loud buzzing because of the fan grilles and filters at the front of the case. Considering the NZXT H440 has 3 front intake, you better off with two fans on the H105 exhausting out of the top of the case. The radiator core is offset so that the side with the fans allows fan screws to clear, while the opposite side has less clearance to allow larger fins for better heat dissipation. Doing God's work, /u/Pianowned. Very nice, good read. I have a Caselabs S8 case with plenty of ventilation to pull cool air in. Another benefit is that the radiator straightens airflow and increases airflow from the front fans. It's really just a disclaimer for the single radiator crowd who are likely to put the cooler in the rear exhaust, where it will also be affected by GPU waste heat. gm is supposed to have a better intake gasket set but last ones i bought a couple of months ago looked the same as i put in in 2005,plastic and some kind of rubber. I'm assuming we're not talking about blower cards despite it looking like there is one in your image. will this make the cpu hot if hot gpu air is in the radiator? A lot of builds do and there’s no issues, More posts from the watercooling community, Press J to jump to the feed. Under high CPU load, radiator blows warm/hot air inside the case, warming up GPU, VRM and other components. Note: I did some informal testing with pull setups. The radiator gets the coolest airflow with the least airflow conflict. Hot air rises, as well as the CPU in in that area of the case in a most common ATX set up. Keep in mind the liquid temperature must be kept below about 45C or the lifespan would be greatly reduced. Intake v exhaust AIO radiator top mounted. Heat from the VRM and GPU make their way to the radiator. CPU block pump becomes the highest point in the watercooling loop and can trap air bubbles. for a cm haf x, more more intake is better. Archive View Return to standard view. Billy Cow. Cases with front doors benefit from sound damping. Otherwise it can put undue stress on the fans and the bearings shortening its life span. Take it on a case by case basis. My current setup has a front mounted radiator as an exhaust and one 120mm fan in the back as intake and two 120mm fans on top as intake. A 120mm liquid cooler was used for the CPU. posted 2008-Jun-9, 4:09 pm AEST ref: whrl.pl/RbyBDd. Dabei seit Nov. 2019 Beiträge 18. The water delta was 4.7C with the fans at 1650rpm and the case + front door open. This would be the same situation just inverted. With a lower overclock, I can finally test with AIDA64 using the FPU. I use the AIO Cooler Master ML120R, and the radiator is mounted on the back, fan exhaust from the inside of the case to the outside on the radiator. Planning on building a computer but need some advice? The result was slightly more fan noise and 1-2C higher temperatures. I will use the Noiseblocker Eloop B12-3 fans, as I found them to perform much like the other fans but with less noise. So pushing that hot air through a second rad is a waste of radiator space. I always thought the lack of proper airflow would tax the GPU temperatures way more. Hi all, I've been bouncing the pro's and con's of … Certain fans are noisy intaking through top venting. Close. 2 x Fractal Design Silent R2 (front), Cougar Vortex HDB 140 (rear). Wiki Points. last updated – posted 2017-May-10, 10:52 am AEST posted 2017-May-10, 10:52 am AEST User #552599 36 posts. Advanced Search; Forum; Cooling; Liquid Cooling; Top Radiator .. Intake or Exhaust? Archive View Return to standard view. I would be mounting the radiator in the top of the case and would look like this setup. Worst performing of all setups. Press question mark to learn the rest of the keyboard shortcuts, Fractal Design Define R4 (without window), Cooler Master Glacer 240L w/ 2 x Noiseblocker Eloop B12-3, Sapphire HD 7970 Dual-X @ 950 Mhz / 1500 Mhz. if the head gasket is blown also it will run hot quick. Keep up the good work. Loudest of all orientations. Many manufacturers recommend that the radiator be installed in a way that it can intake air from outside the case with the fans pushing air into it. Exhaust fans at the rear can also cause airflow conflicts and do the most damage to radiator temperatures. either way, doesnt really matter too much. does intake or exhaust matter for a radiator matter. 6 years ago. Lowest noise for those cases. Is that optimal for temps? When people build custom loops, the pump is usually at a lower point and is constantly fed water by something like a reservoir to ensure quiet and reliable operation. does intake or exhaust matter for a radiator matter. EXTREME Overclocking Forums > General CPU Cooling > Water Cooling - (Plain & Chilled): Radiator on intake vs exhaust side For now I use 2 intake bottom, and 2 exhaust back and side. posted 2017-May-9, 3:42 am AEST ref: whrl.pl/ReTrLh. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc However, depending on the CPU load, the rest of the case may get warm air, which can hurt GPU and VRM temperatures. Follow 11689. Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. It's a trade-off between CPU and GPU temps. Im also using an aio as the example as if you've only got one radiator it is extremely comparable. But intake would be more ideal. Radiator intake or exhaust? With the radiator at the front, the pump becomes the highest point in the loop and can trap air bubbles, making the pump noisier. At 100% CPU load with my current overclock (4.6 GHz), my GPU seems to be running at least 3-5C hotter with the radiator mounted at the front. The temps will be affected significantly after a while for the top intake without any filtering in a dusty house. Whirlpool Enthusiast reference: whrl.pl/Re87Nq. Radiators are kind of dust traps as it is, which is amplified when using as an intake and even further when it's the top, where dust naturally settles. Difficult install. Finally, many CLCs and ready-to-run open loop coolers (H220/Glacer 240L) have a pump/block combo which means the pump sits at a high point. If you have filtered intakes elsewhere, though, would be fun to try it. Both components will be cooled the same. People will bring up the fact that hot air rises, but that is negated by forced airflow. more intake than exhaust increases pressure in the case which forces air out the case faster as air always flows from regions of high pressure to regions of low pressure. I would be mounting the radiator in the top of the case and would look like this setup. NashaK. Top fan spaces are free to close off or add even more fans. I had the fans in push (exhaust) under the radiator, but it got to be a pain removing the fans to clean cat hair buildup. While what MNMadman said might be true in rare cases, fan airflow is basically the result of the pressure differential between intake and exhaust sides of impeller, .. and as such impeller has no idea if radiator is in front or behind it. The air coming out of the intake radiator is about the ambient temp + 60-70% of the water delta. would it work better if the top radiator was intake and I made my front panel exhaust? I'm new to water cooling and just bought a corsair aio. But all in all the difference arent that big as i would have thought. I'm getting a NZXT H440 and I was going to put the H105 in it but I can't figure out wether to use it as an exhaust or as an intake. Keep up the good work. TDuiker. I ran two lots of tests. On the intake side, I purchased a Minnam intake, for my OBS, used that cost me $20.00. I just can't decide if I want to set the H100i up as an intake with the fans below the radiator pulling down into the case, or if I want it set up as an exhaust with the fans above the radiator pulling up out of the case (I'm only suggesting pull configs because of easier dust cleaning). Question. Air stays trapped at the radiator, not the pump. If it's possible you could just put the radiator in the front and solve the problem the "normal" way. posted 2008-Jun-9, 4:09 pm AEST O.P. It doesn’t matter. Followers. So far, the only ready-to-run open loop cooler that tackles this issue is the Swiftech H220-X where the pump and reservoir are one and the same, mounted to the radiator. posted 2018-May-5, 5:51 pm AEST O.P. Ersteller des Themas GushO; Erstellungsdatum 5. But .. and it's a big 'BUT' .. the exhaust side of a fan has impellers 4-5mm farther away from fan mounting surface (fan housing) then on intake side. Bottom radiator, intake or exhaust. Desweiteren sollen drei zusätzliche 120mm-Lüfter als Intake, zwei 80mm-Lüfter als Exhaust dienen. If you have both exhaust and intake fans, you should ideally balance the volume of air moved. To conclude, it's all about finding which configuration works for you. Results. Warm air pushed inside towards VRM and RAM (remedied by having rear exhaust). I think it's worth it for the sake of 2 degrees C and a load of convenience to go front intake or, for minimal effort, top exhaust. Silence freaks may mount the radiator to the front of a silence case, while someone who isn't too worried about maximum CPU overclocking but wants the GPU to run a bit cooler can do a radiator top exhaust. I was in the same location for both tests. Question. So, if you want optimal overall temps, you should give your radiator fresh air. Press question mark to learn the rest of the keyboard shortcuts. Top mounted radiator, intake or exhaust ? Im fitting a 3 fan radiator to my Cosmos S case at the top.. Jonnybmac. I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. In fact, the Glacer/H220 is designed with this in mind with a reservoir and fill port that helps bleed the system of air when the screw faces up. You'd think with "a couple degrees" difference between rad intake and exhaust, it wouldn't much matter having a radiator placed coincident with exhaust. One was a gaming test, which consisted of me running 7 Days to Die standing in my base looking at my two forges until the temperatures leveled out (for some reason this taxes the system a lot). The AIO will either use the hot air from the gpu as cooling or expell hot air into the case and make the gpu run hotter. Theoretically yes. This allows the radiator to get the coolest intake air from outside the system. The temp difference will be a few degrees at best realistically it will make zero difference in how your system runs. was the head gasket blown or just the intake? Edit: this statement is actually correct. H220/Glacer 240 specific: Fill port faces up, allowing air to bleed out slowly. the reason i ask is an intake will put exhaust in the radiator and make it use little water. Also, as per everyone else's recommendation, it is best to have exhaust fans on top or upper rear of the case. posted 2017-May-9, 3:42 am AEST O.P. Under low CPU load, the radiator acts as an airflow straightener without warming up the air, so the fan can blow cool air more effectively inside the case.
