Bad H100i V2 (poor performance VS my Hyper 212 Evo)

[Crossvxm]

I recently purchased a Corsair Hydro Series H100i V2 to try to finally get into the Intel world of overclocking (I've always used AMD in budget builds and my first Intel processor was an i3 4130T). Almost every part in my current build was purchased early 2017 with the exception of the motherboard and one of the HDDs (Seagate). The processor being used is an Intel Core i7 4790K at "stock" speed (more on the quotations soon). The Cooler Master Hyper 212 Evo is of course one of the best options not only because of its price, but because of its overall performance. The H100i V2 was a DISASTER, something I have never experienced even with my final AMD build using an FX 8370 along with the H100i V2. Temps on AIDA 64 with the 212 Evo tops out at high 70°C in the last test I performed for 2 hours right before the H100i. I'm not going to mention Prime95 as its latest version is extremely brutal on any Intel CPU, and this has been mentioned by others (it will take your temps far above what any game or other well known benchmark ever will). The H100i however was merely acting like a bare heatsink. Idle temps were around 39°C and any light processor usage would kick it up to 45 - 55°C whereas the Hyper 212 Evo always sits in the low 30s, and would reach about 36°C with light processor usage, low 40s when opening an app. Firing up AIDA 64 made the temps reach 100° C in a matter of a minute and I IMMEDIATELY stopped the test (I have perfomance mode as my power preference in Windows 10, which keeps the CPU always at its Turbo speed instead of stock 4GHz). I knew it wasn't the thermal paste application as I always get it perfectly even and precise on the first try on any CPU, any IHS ("lid") size (I use the pea method as it is the way I was taught and has never failed me). I removed the pre-applied thermal paste as I prefer my MX-4. I retried three times, each time was a perfect application, each time same issue with the temperatures. Kicking up the pump speed and fans to the max with Corsair Link seemed to help VERY slightly (temps reached about 87°C struggling to keep low which still isn't normal for any AIO). Fans are working perfectly (exhausting air up) and the pump seems to be working as per Corsair Link. Internal temps are usually slightly cooler than room temperature, which is the way I currently maintain my indoor ambient temperature. I'm about to return the H100i V2 as I can't think of anything else but the thing being faulty.

Sorry if this is a bit of a novel to read. Any advice, or did I answer my own question? For a complete breakdown of my exact components, see the link below (the only things missing in the list are my Kingston HyperX Savage 480GB a Corsair AF120 red LED fan for the rear exhaust and of course the H100i).

Well since you installed Corsair Link, Open it up and where is says H100I and if should give you pump speeds temp LED, click on the pump RPM and set the mode to Performance, you should get a graph and RPM Readout if the pump is working.

I've seen a few of these H100's that were just dead, pump would not do anything but the system usually would stay cool enough to still idle in windows. The H100I should out perform the 212 by 5+ c in most cases, your 4790k should not get much above 60C.

Make sure the pump is working, I typically plug the pump directly to the PSU with a molex adaptor since some motherboard fan headers will control the fans and the pump doesn't need to be controlled by the motherboard as it does it itself or the via Corsair Link.

Also check voltages, if you tried to OC the CPU even enabled XMP on the RAM, it can OC the CPU and automatically raise the CPU voltage higher than what it should be, You can check this with HWmonitor form CPUID which will tell ya pretty much everything you need to know temp and voltage wise.

I have a original H100 that still cools a FX8320 at 4.6ghz, I've had it for 7 years I think. And I use the H100I GTX on my i7 5820k at 4.5ghz, I don't get much above 60C in a warm room.
