MSI Cooling Core Frozr XL

I recently bought a really nice custom-built computer off Craigslist when the previous owner decided to upgrade. The specs included an Intel i7-6700, Gigabyte GTX 1080, and MSI Z170a Gaming Pro Carbon. The computer came in a gym-locker-sized full tower case that needed to go, and the CPU was cooled using a Corsair AIO cooler (I'm not sure which one...I'm not a big fan of AIO coolers). I don't know if it wasn't seated properly of if the thermal paste had dried up, but the cooler was doing a terrible job. The CPU idled around 50C and under moderate 4k gaming topped out around 90C. The previous owner had been running the build as-is for about 4 years, so maybe it was just dried up thermal paste. While in the process of transferring everything to a new case that would actually fit ...well...anywhere useful, I decided to get rid of the AIO. I bought this MSI cooler, having never used an MSI cooler before, but it looked cool and the TDP dwarfed my needs. I was shocked, SHOCKED I TELLS YA, at the difference I saw once in the new case. Granted, some of that could have been airflow through the case, but the old case should've flowed just fine. My new idle temps were between 25 and 30C, and under the same loads the CPU peaks around 60C! I now use that PC with my new Steam Index VR set and even hitting 100% on multiple cores during the process of a session the CPU never tops about 68C. Really impressed with this thing! Installation was simple and well thought-out (despite so/so directions that were 95% pictures). It came with a tube of thermal paste that I opted to use (in order to test it how MSI intended). The description actually states how tall a ram stick it'll clear which is EXTREMELY convenient, because that's usually an unknown. It cleared my non-LED Corsair Vengeance sticks without adjusting the fans up at all. Overall, really nice looking, VERY functional unit! Extremely happy with my purchase, and by far the best price found here. If you can fit it, buy it.
