Starting off, I'm posting this info so that people who are thinking about switching over can get an idea of what to expect. I used the EVO and it wasn't working out for me. Got myself an H100 for cheap and someone asked for some temp comparisons. This is NOT to bash 212, this is for anyone like me who felt their 212 unit isn't working out for them and may be looking elsewhere.
Alright guys here we go. H100 has been installed, it wasn't easy but I managed
For reference I'm using an NZXT Phantom case two 200mm fans up top. One silent fan in the back top running 700rpm, one performance fan in top front running at low speed. It can go up to high speed 1300rpm I believe. I have mounted the radiator underneath said 200mm fans, with two ap-15s pushing the air upwards towards the pull fans. H100 is set to performance mode, level 3. My Evo ran in a push and pull config using the ap-15s. CPU is FX-8120.CPU 3.8ghz 1.24 idle to light load. Youtube videos at 1080p, etc.Evo
: Idle temp at at fans full speed 33-37 degrees under light load. Core temps at around 20 degrees each.H100
: Idle temp with fans at low speed 31-34 degrees under light load. Core temps at 16 degrees. (Notice that this is at low speed, fan speeds adjust to temps)CPU 3.8ghz 1.24v under OCCT stress test. Both tests ran for just 30 minutes.Evo
: CPU temp ranging from 58-63 degrees at full speed each fan. Core temps baseline at around low 50s and rise over time to high 50s, would often raise up and then lower. Thus keeping inbetween max temp and lower temp. At time of recording, 58 degree core temp. CPU temp seemed to stay between 60-63.H100
: CPU temp topped out between 52-55 degrees at low speed. Core temps between 36-40 degrees, staying at 37 for the most part. That in my opinion is solid, my system also seems to be decently quieter than before.Further testing
: 4.2ghz at 1.32vcore (could probably play around with that voltage a bit... Don't think it needs to be that high for 4.2) 222 bus speed, 19.0 CPU multiplier. 1 hour OCCT test Max CPU temp 61 degrees. Tends to stay around 59. Core max at 48, stays around 44. A 4.5 stable seems unlikely, my chip still is a hot son of a gun. When I get to 1.4+vcore things get a bit too warm at times. I'll play around and see if I can get to 4.3-4 however.Edit 1
: So, oopsie
It seems that the fan controller on my H100 doesn't work. No matter what configuration it's at the fans stay at the same speed. Turns out all those temps are with fans running at low speed. Good thing I have this lovely NZXT phantom case (love it) that has a built in fan controller. I decided to disconnect the two side fans from the control and plug in my ap-15s instead. Now I have manual speed. I doubt it'd make a huge difference however next time I stress test I'll have fans set on high. I'm tempted to toss on OCCT and see if there is a difference. We'll see.
Temps are relatively close at idle under 3.8ghz. Under OCCT stress test we can see that while CPU temp stayed a decent 5-10 degrees cooler. Core temps were the big story staying under 40 degrees. That's a 20 degree difference compared to air cooling. And that, my friend, seems to be a pretty good result
For reference again, 3.8ghz is about the best I could manage with the temps I got. The FX series recommends core temps stay under 62 degrees, give or take some room. With my Evo I was barely hovering under that. I'll update with higher OCs and temps to go along with it.Edited by Xerosnake90 - 9/29/12 at 11:44pm
