I just got my Cooler Master Glacer 240l, upgrading from a Noctua NH-U14S, and I figured I would do a detailed, precise as possible comparison to see just how much of a difference this would make. A little background before we begin. First, I bought the Noctua because in reviews, it came very close, or equal to the Corsair h100i cooler and I wanted to try and get more overclocking headroom over my then Cooler Master Seidon 120m. While it was a better performer and gave me a little extra wiggle room, ultimately the difference wasn't too huge. Wanting to go to liquid cooling for my entire system anyways, I asked for advice and was told resoundingly that the Glacer was a BIG deal. Is it? Let's go to my testing method and some screenshots of my results.
So I started my testing first thing in the morning. Started my computer from being shutdown all night, then went right into an OCCT stress test. Right after turning the test on, I then started my HWInfo monitor to have an accurate Highs and average temps. My Noctua cooler (which has a dual fan setup btw) was previously installed with Prolimatech Pk-1 thermal paste and while I've not noticed any significant difference from "cure time," the install was done months and months ago so everything would have been settled in plenty by now. My AMD FX-8350 is overclocked to 4.5 Ghz and my Vcore maxes out at 1.45v during stress testing (This is a Digi + feature with my Asus Crosshair V Formula-Z Motherboard). I ran my test for 30 minutes. These are the results I had with the frequency, Temps, and Vcore circled in red.
Once I had the results, I shut down and began the process of installing the Glacer. While I don't remember the exact time frame I believe it was a couple hours of install which meant my nice cool morning was starting to fade into a warmer late morning. I once again used the Prolimatech thermal paste, but this time there wasn't any "cure time" due to starting the computer up and beginning the test immediately. So just like the last time, I copied all the same steps for running the test with the monitor and waited for 30 minutes to see my results.
So now I officially know that everyone lied to me. The Glacer isn't a BIG deal, it's the best thing that ever happened to the AIO market!!! I'm just kidding about everyone lying to me. The reality is I was told how much better the Glacer was, but having never seen such a huge difference from cooler upgrades, my skepticism remained ever so slightly. Keep an eye out for updates, because the next step will be finding out how far I can take my cpu now that I know I have a lot more thermal room to play with.
Oh, and here's some numbers. The Glacer dropped my average core temp by 12.2c and my Maximum temp by 14.7c!!! Those aren't everday drops!
