So sure locking the fan speeds at say 50% would give me the best and most accurate CPU temperatures for both mounting points but my aim was to do a more real-world test. 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). If you want to showcase all of your fancy gaming components and water cooling loop then this open frame panoramic viewing case is a perfect choice. Need to mount your reservoir to your case, radiator, fans or even externally on a stand? The GPU, however, did not run any cooler under gaming, which was to be expected. 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). And this is the system with a top mounted radiator: One thing I did differently to the other tests I have seen is not locking any fan speeds in the system, so the GPU/Radiator/case fans were set to the default quiet curves. Three cases with unique qualities were chosen for this test: the S340 Elite (relatively normal layout), the SilverStone Redline 06 (unusually high airflow), and the Corsair 600C (inverted motherboard). The differences are big enough however, that I would recommend mounting the radiator at the top of your case, exhausting air out. A note on charts: two configurations are compared in each chart, and the lower temperature between the two is highlighted green for each component. Heat from the VRM and GPU make their way to the radiator. The radiators are designed to fit into a standard fan mount (usually 120mm) on most PC cases. I will certainly take this into account for when I upgrade my system. This question gets asked every year, it seems, and is worth a revisit: Where in the case should I put my liquid cooler? We have all the clip, bracket, holder and 5.25" bay mounting hardware … The differences are big enough however, that I would recommend mounting the radiator at the top of your case, exhausting air out. My aim was to find which way gave the best overall results, sure the front mount gave better CPU temps but at both locations the tempritures were both very acceptable and the fans didnt have to speed up much at all to compensate, but with the top mount the GPU fans had to work less to keep the card cool due to not having to also disipate the hot air coming from the CPU rad. This is pretty interesting and I didn't expect to see quite such a difference. If quiet computing is your thing and your GPU is air cooled, then the top of the case is the way to go. I assumed that the GPU fans had to work a lot harder due to hot air from the radiator being dumped onto the GPU, as you can see below they are quite close to each other. Before I show my results I will say that the case I am using is fairly shallow and the front fans/radiator are quite close to the GPU. For example, some mid-tower like Corsair 570x allows you to mount 2×120 or 2×140 radiators on the top. Radiator has to go on the top (only place I can fit a 360). One good mounting position is to mount the radiator of the cooler at the frontal area of the case interior. In the very least, we can look at liquid cooler placement performance in a few different cases. Shorter cases are becoming more popular now since we ditched the optical drive though :). Also, take note of the radiator thickness! In fact, that spot may not even be the best place for it. But, when it comes to PC cooling, sealed all-in-one (AIO) liquid cooling systems—also known as closed-loop coolers—are safe, effective, and easy to install. With a longer/deeper case there may not be as much of a difference. The CPU temperatures were a little higher when the radiator was mounted at the top during gaming and was around seven degrees higher under Boinc, but were still well within safe limits and the fans did not have to speed up to compensate. Likewise, 240 and 360 radiators will usually mount if you have two or three adjacent 120mm vents. Temperatures should stay fairly similar all round with each configuration, but would the fans spin slower on one configuration over the other to maintain the same temperatures? The boost clocks were also slightly higher, which is always a bonus when gaming. With the pump set to “silent mode,” which establishes a pump speed based on the liquid temperature, CPU deltas should have been at least slightly higher with other temperatures less affected. Here’s a look at the configuration, though we obviously used a radiator (X42) instead of the air cooler: Results for the S340 were consistent with the RL06, which has the same conventional front intake, rear/top exhaust system. Fans attached to the coolers remove waste heat from the radiator. This will install the Radiator programs and libraries in the standard places, and will create a basic Radiator configuration file in C:\Program Files\Radiator\radius.cfg and a sample users file in C:\Program Files\Radiator\users. We sort of had to hack the solution together, seeing as our VRM heatsink and RAM wouldn’t allow a top-mounted radiator (X42) to clear. Talk about versatility. With the front mounted radiator blowing out, the reviewer doesn't indicate where or which way the two NZXT fans are blowing, in or out. Nice one Plat, especially like the graphs. Water has a high thermal conductivity, meaning it absorbs heat very easily—even moreso than air. Clear PC interior of anything that may obstruct installation. The side of the radiator where the tubes connect should be at the bottom, and the pump should be mounted in a position where it is slightly lower than the top of the radiator, where air is captured. Cheers :) Big thanks to wowky for the graphs :), CD Projekt Responds to Class Action Lawsuit, Billion Beat Receives Steam Early Access Release Date, Resident Evil Reboot Movie Has Finished Shooting, The GrinCast Episode 284 - Retro Retrospective, S.T.A.L.K.E.R. My investigations into this lead me to believe that the placement does actually make a difference and, depending on your case, can make a big difference. Thermaltake Core P5 Tempered Glass Edition ATX Wall-Mount Case. I planned to mount the radiator into the front (filtered material there and intakes in the front panel in the Fractal Define S Window) with the fans pulling air through the Radiator into the case. I was in the same location for both tests. Some cases would allow this more readily. Every single component impacts internal case thermals, and that means that the best anyone can do is create a system analog that reasonably represents most builds of a certain type. This includes measuring how much a front radiator might reduce CPU temperatures at risk of raising GPU temperatures, or how a top-mount might do the opposite. 2 Skif Introduction Trailer, Monster Hunter World: Iceborne Top Tips For Using Lances, Monster Hunter World: Iceborne Top Tips For Using Great Swords, Monster Hunter World: Iceborne Top Tips For Using Charge Blades, Monster Hunter World: Iceborne Top Tips For Using Hunting Horns, The GrinCast Episode 283 - Game of the Year 2020 Part Two, CD Projekt Responds to Class Action Lawsuit, Intel Core i7 7820x CPU @ 4.3GHz (Voltage set to auto). Check PC specs against potential liquid cooling unit to guarantee compatibility. This was not an article I was ever planning to do. Interesting to know. The case alone has a huge impact on thermal performance, next dictated by the fans and coolers within the system, then the video card (how do its fans behave? Starting with radiator placement testing, we’re using the new EVGA 240 CLC as a stand-in for top versus front mounting tests, measuring both GPU … All fans will be configured to 100% in our testing. This article was written by Steve Burke & Patrick Lathan from GamersNexus. The CPU temperatures were a little higher when the radiator was mounted at the top during gaming and was around seven degrees higher under Boinc, but were still well within safe limits and the fans did not have to speed up to compensate. To avoid making your computer too loud, use fewer or quieter fans. We have other cases tested in our article on GamersNexus, but the foundation is this: It depends on the case and the cooler. The two configurations tested are more directly comparable than they were in the RL06, since the direction of airflow did not significantly change. I wish I had a decibel meter but instead, you'll have to take my word for it. So yea I should have been clearer stating that this was not a "which cools the CPU better" article, I will try better next time :). « NZXT Kraken Guide: How to Optimize for Silence and Performance Is … The best PC cases offer a jumping off point for your gaming PC build, but can also be the finishing touch that makes your machine stand out from the rest.You have a wide selection to choose from, too For some of the other cases we tested, we generally found that front-mounted radiators always raise GPU temperatures as the CPU heats up. Think I'm going to go with intake (at least until I upgrade my GPU with full block. The blower cooler video card (most stock cooler designs) saw little difference between a top and front mounted CPU radiator. Yea that will definitely give you the best cooling. Do: Mount the radiator so its airflow is not impeded by other devices in the machine. Just mount it where it fits best. Personally, before I switched back to air, I actually had the rad mounted outside of the case entirely, and if you can manage that, then I'd recommend that as the best way, but it's a tricky thing to do. More case fans means higher total CFM and more air being moved through your computer. CPU stays much cooler while the GPU is unaffected. In the S340, results were consistent between load and idle testing. I always assumed that radiator placement made little difference to internal temperatures, I even backed up my thoughts on this by checking out a few YouTube videos. Cheers mate, This was an interesting one to do and I learned a few things in the process. I stuck with the same project (Asteroids @ Home running both CPU and GPU workloads) to try and keep things a fair as I could. Is the NZXT Kraken Compatible with AMD Threadripper. Knows more about hardware than safe drinking limits. Buy Lian Li PC-O11 Dynamic Mid-Tower Case. There were no anomalies in ambient temperature, CPU load, frequency, or voltage, but differences this small could be attributed to test variance, especially with the added complication of a pump speed curve. For radiator testing, we simplify matters by eliminating the various air coolers designs – liquid coolers ultimately use parts that are easier to compare. I ran two lots of tests. Placing a sheet of foil-faced, expanded polystyrene lining behind the radiator will ensure that heat is reflected back into the room, instead of being lost through the outside wall. In conclusion, the results show that there is not a huge difference when gaming, but still noticeable from a noise point of view and there is quite a difference when running Boinc (great for people like me that run it 24/7). For example, a 480mm radiator can hold four 120mm fans, while a 280mm radiator can have two 140mm fans attached. Water cooling I don't think anyone runs there fans at locked speeds, most will use the normal/silent bios presets or run with their own custom presets so this is what I did. With the radiator up top, you've got 3 fans exhausting out of the case plus the GPU exhausting air as well. The 240mm radiator, however, is thicker and has tighter packed fins. So I seem to be getting some flak on social media / Reddit for this one for not testing with the fan speeds locked, I wasnt as clear as I could have been in the article about my intentions so let me try and clear this up a bit. CPU temperatures were predictably lower when the radiator was placed in the path of unwarmed in-flowing air, while GPU temperatures were lower when inflowing air was not warmed by the CPU. Remove PC’s factory fan assembly and heat sink protecting the CPU. Case testing is one of the least exact sciences, because it’s simply impossible to control for every possible variable. Ultimately, we generally recommend trying to keep the GPU out of heat paths as most have a temperature ceiling of 82-85C prior to clock throttling – and GPU clock throttles are more noticeable in gaming performance. Take a look at this guide to figure out the right radiator positioning for you. This article will just focus on the NZXT S340 Elite. Install Radiator with perl Makefile.PL install. This is the key thing for me as I like having a quiet computer. But if you have a thick radiator or high-profile RAMs, things become pretty annoying. One of the best spots on a machine is the top of the case. This is the system with a front mounted radiator: (It's a little hard to see, but there is a radiator behind the two front fans). The main difference between placing the radiator at the front and top is that a radiator in the front could heat components inside the case and a radiator at the top could pull hot air from inside the case through the radiator which could heat up the CPU. In the videos I had watched most had locked the speeds to 60% or so in order to measure temperature changes but I found that 60% didn't make that much difference to temperatures but did produce unacceptable noise levels (in my opinion). If … So I decided to do some testing myself and find out the answer. This makes sense, since the front-mounted radiator is dumping heat onto the GPU. NZXT Kraken Guide: How to Optimize for Silence and Performance. So that just leaves 1 final question --ROOF FANS \/ \/ RADIATOR or ROOF RADIATOR FANS \/ \/ I used two AIO coolers for this test, one is a 280mm (EVGA CLC 280 Liquid CPU Cooler)  and the other is a 240mm (Corsair H100i V2). And 1080 is the EVGA Classified so not a blower. CPU temperatures rise a little bit if the cooler is rear-mounted, but there are a few important things to note here: One, CPUs are way more tolerant of temperature fluctuations than GPUs, and also have significantly higher thermal ceilings; two, GPUs won’t dump heat straight into the CPU cooler (generally speaking), so the impact of the CPU temperature on the GPU is more profound than the inverse.
