It's a trade-off between CPU and GPU temps. Top mounted radiator, intake or exhaust ? does intake or exhaust matter for a radiator matter. Sorry if this sub is just meant for custom liquid cooling, this is the best place I thought I could ask. Whirlpool Enthusiast reference: whrl.pl/Re87Nq. The radiator … 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. Filtered, fresh air from the front (though slightly restricted). 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. A really interessting test considering that top intake is the best cooling option in this case. Another benefit is that the radiator straightens airflow and increases airflow from the front fans. Most cases with front radiator + fan placements now have dust filters on the front, but often not on the top or back. :]. posted 2018-May-5, 5:51 pm AEST O.P. I ran two lots of tests. would it work better if the top radiator was intake and I made my front panel exhaust? Basically one of those things where it's just personal preference. The dust thing can't be overstated. CPU block pump becomes the highest point in the watercooling loop and can trap air bubbles. 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. Very nice, good read. Im fitting a 3 fan radiator to my Cosmos S case at the top.. Both components will be cooled the same. To conclude, it's all about finding which configuration works for you. This should provide more consistent results than using BOINC's Rosetta@Home. This is the place to ask! If the radiator fans are exhausting, they would be pulling hot air from the gpu through the radiator. Theoretically yes. 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. 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). I went with dual intakes and did some testing in my Define R6. 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. Close. So here goes! Loudest of all orientations. Billy Cow. But intake would be more ideal. This topic is locked from further discussion. Keep up the good work. 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. Otherwise it can put undue stress on the fans and the bearings shortening its life span. The manufacturer recommendation of having the radiator intake from the top is a good recommendation. NZXT Grid w/ Fractal Design 3-speed fan controller, Gigabyte EasyTune, Unigine Valley 1.0, Extreme HD preset, Windowed 1920 x 1080, 8xMSAA. Archive View Return to standard view. Using radiator as intake on the other hand hardly effects GPU temps in game. Certain fans are noisy intaking through top venting. If you have filtered intakes elsewhere, though, would be fun to try it. Is that optimal for temps? either way, doesnt really matter too much. 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. Very muted fan noise, very faint pump noise. Under high CPU load, radiator blows warm/hot air inside the case, warming up GPU, VRM and other components. Worst performing of all setups. The full test methodology is available in the GamersNexus reviewand was used throughout this cooling optimization test. posted 2018-May-5, 5:51 pm AEST ref: whrl.pl/Re87Nq. Archive View Return to standard view. Results. Edit: this statement is actually correct. Top mount radiators - Intake or Exhaust fan setup? Followers. last updated – posted 2008-Jun-26, 4:46 pm AEST posted 2008-Jun-26, 4:46 pm AEST User #183846 445 posts. NashaK. Desweiteren sollen drei zusätzliche 120mm-Lüfter als Intake, zwei 80mm-Lüfter als Exhaust dienen. Wiki Points. A 120mm liquid cooler was used for the CPU. i prefer more intake than exhaust, but thats because my silverstone raven 2 works better that way. As suggested above, I would certainly set the H115i fans to exhaust heat out the top. Radiator uses warm air. However, depending on the CPU load, the rest of the case may get warm air, which can hurt GPU and VRM temperatures. Radiator intake or exhaust? for a cm haf x, more more intake is better. Intakes fresh air from the top, runs coolest. OR having a few more intake than exhaust fans can be helpful. Cases with front doors benefit from sound damping. Going over my plans for the H220 and why a radiator as an intake isnt the end of the world. I was thinking about trying something similar with the h220x I pre ordered... New comments cannot be posted and votes cannot be cast. 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. 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. Who knows about the VRM/Mosfet though. 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. Reviews: 0. The radiator gets the coolest airflow with the least airflow conflict. 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. :] level 1. 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. Hallo, ich werde am Wochenende in das Lian Li PC-O11 Air 3x 30mm 360 Radiatoren einbauen. Discussion in 'Overclocking & Cooling' started by Jonnybmac, 11 Aug 2019. 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. I was in the same location for both tests. However at 4.6Ghz, the radiator and the air coming out of it is very warm and can heavily affect internal case temperatures. The other custom XT6 exhaust was around $500 including the header and a cat converter I supplied. Top fan spaces are free to close off or add even more fans. Hi all, I've been bouncing the pro's and con's of … 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. 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. Question. With the radiator at the front, the pump becomes the highest point in the loop and can trap air bubbles, making the pump noisier. A bottom intake fan is recommended. The front mount lies in the middle in terms of cooling for the radiator. I'm new to water cooling and just bought a corsair aio. 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). 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. 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. Rear exhaust fan steals air from radiator. posted 2008-Jun-9, 4:09 pm AEST ref: whrl.pl/RbyBDd. I would be mounting the radiator in the top of the case and would look like this setup. Jonnybmac. Posted by 5 days ago. 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. last updated – posted 2017-May-10, 10:52 am AEST posted 2017-May-10, 10:52 am AEST User #552599 36 posts. So i have these 2 options ( blue rectangles are intake fans, red are exhaust ) : If it's possible you could just put the radiator in the front and solve the problem the "normal" way. I was watching some youtubers put the radiator in front and have it serve as an intake instead of exhaust. Also, as per everyone else's recommendation, it is best to have exhaust fans on top or upper rear of the case. The GPU (GTX 980 Ti) was using an NVIDIA reference design cooler (blower fan), which will yield … Anyone is welcome to seek the input of our helpful community as they piece together their desktop. However, depending on the fan you use, you may incur a heavy noise penalty (the Noiseblocker Eloop is a great example of this). 2 x Fractal Design Silent R2 (front), Cougar Vortex HDB 140 (rear). 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. Wise Guy. This would be the same situation just inverted. posted 2008-Jun-9, 4:09 pm AEST O.P. Warm air pushed inside towards VRM and RAM (remedied by having rear exhaust). 5. Planning on building a computer but need some advice? However, you may need to invest in some air filters for the rear fan. 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. If you have both exhaust and intake fans, you should ideally balance the volume of air moved. Advanced Search; Forum; Cooling; Liquid Cooling; Top Radiator .. Intake or Exhaust? Show only OP | 11 Aug 2019 at 21:47 #1. 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. Air stays trapped at the radiator, not the pump. 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. Follow 11689. Intake v exhaust AIO radiator top mounted. The temp difference will be a few degrees at best realistically it will make zero difference in how your system runs. 6 years ago. Should I be: a) pulling "fresh" air in from the top of my case through the radiator. I will use the Noiseblocker Eloop B12-3 fans, as I found them to perform much like the other fans but with less noise. The water delta was 4.7C with the fans at 1650rpm and the case + front door open. https://www.maketecheasier.com/intake-exhaust-fans-airflow-desktop-pc So, if you want optimal overall temps, you should give your radiator fresh air. I'm assuming we're not talking about blower cards despite it looking like there is one in your image. 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. 36 posts pump becomes the highest point in the same location for both tests exhaust but.
