WindyRain0212 Posted March 25, 2017 Share Posted March 25, 2017 So I did an RMA about a week ago to replace my trusty H100i (it's cooling efficiency degraded highly and there was a lot of air in the loop). Got a H100i v2 in return. Nice, yes? Nope. Problem: The whole pumpblock is so loose on the CPU that I hit 100+°C almost instantly as soon as I start a stress test (and that on 4.0 GHz / 1.0v, CPU is in the profile) - The coolant temperature would idle on a chilly 32-38°C (Also using Corsair's preapplied paste, which was pretty dry, is that normal?) I could move it around.. ~5mm while it's installed. I attached an image of the backplate and how far it goes off while the pump is installed. Another thing I noticed is that the standoff screws don't fully screw into the backplate - if my memory serves me right they do on the H100i. Now after those temps I looked around the forum and saw some similar topics. I also read somewhere to try washers, so I took 4 from the 8 of the radiator mount screws and put them on between the motherboard and the standoffs. Swapped cooling paste and now the temps are around 80°C (~41°C coolant) when gaming. Running a stress test or high usage still skyrockets it to 90°C and above though. For comparision: H100i temps @ 4.7 GHz , 1.37v: CPU: 73°C / Coolant: ~50°C All aforementioned stresstests are AIDA64 Extreme System Stability tests (CPU,FPU,Cache,Memory) Now I want to know, is there anything I might be missing onto why its THAT loose without the washers and/or is there maybe a better way to use the washers for increased performance? I was extremely happy with my H100i, but the v2 only surprised me when I opened the package.. The rest is a dissapointment so far. :(: I also contacted the support yesterday, but answer from there will only come on Monday. Link to comment Share on other sites More sharing options...
