### ⭐⭐⭐⭐⭐ Great for starting cooling pc builds
*by S***C on May 8, 2025*

Fantastic all in one place. I had this running in my build for while now and haven’t had any issues. Always keeping my pc at low temps as much as possible.

### ⭐⭐⭐⭐⭐ Completes any high-end build
*by J***H on May 1, 2023*

Prior to install, my CPU was running near 87 Celsius during CINEBENCH R23 benchmark. I had to pull back voltage, and thus had to pull back MHZ. My GPU was running around 85 Celsius during intense game play. Now, after installing this monster cooling system, my CPU is running at 78 Celsius during CINEBENCH R23, and my GPU is running at almost the same temp +/- 2 degrees. They both idle at 34 degrees Celsius! They used to idle at 50. I was able to now overclock without any voltage issues causing thermal throttling. I went from a CINEBENCH R23 score of approximately 28000, to 31,940. Worth every penny. However, the included saw isn't great. Get an upgraded tube cutter and buy a few extra tubes. You'll be happy you did. I did add one more radiator and set of fans because of the stress my system goes through, but you should still get quite a reduction in temps with only the one set included.
