I just finished installing the Noctua NH-U12P SE2 and didn't get the expected results.....
I'm running an Antec 300 (with 2 Noctua NF-P12 fans in the front and another one on the side, in addition to the top and rear fans) + Intel E8400.
It's worth noting that this is my first time installing a CPU cooler and that I installed it so that the hot air is directed up, towards the case's 140MM blowhole fan.
Before I switched the cooler I got a stable idle temp of 44C on both cores with the intel fan and about 55-60C on load. (Ambient is about 25C).
I read on countless reviews how the Noctua cooler is supposed to reduce my temps but after switching to it my idle temp is 42C on one core and 37C on the other, load temp is just below 50C.
When I overclocke to 4Ghz, I get 50C at idle and 65-70C on load.
Is that normal temps for that kind of cooler and CPU? because in most of the reviews I read the cooler had lower temps on CPUS that are mush hotter than mine (like the i7 and C4Q EX)....
Any insights would be greatly appreciated.
What thermal grease are you using. If it is AS5, it needs curing time. Some do and some don't.
I am using the included Noctua NT-H1.....
Also, when I said that I just finished installing it, I didn't mean right this second.... It's been over a week now. I also tried the 0.4mm blob method and got some 2-3C lower temps on load / overclock, but not on idle.
Your TIM may need to be reapplied. You may want to consider some other TIM. IC Seven Carat is highly rated, so is Shin Etsu. if you can find it. AS5 is fine.
As I mentioned earlier, I tried both the "Thin layer" method and got the results above, and then I tried the "0.4mm blob" method and got some 2-3C lower temps on load / overclock, but not on idle. So yes, I already reapplied it.
I don't have a specific problem with changing the TIM, but It should give me better results with the included TIM.... :-\
"IC Seven Carat is highly rated, so is Shin Etsu. if you can find it. AS5 is fine."...... How is the AC MX3? I read some superb reviews about it. Is it better than the ones you mentioned above?
Could it be that the top case fan is so close to the top fan on the cooler? (they are both blowing air in the same direction)
MX3 is really good, too. So is MX2. If the case fan is exhausting the heat, that is they way it should be. You might want to try having your hsf venting the air to back of the case. Do you have a rear fan? I see tha you have 2 front fans a top mounted fan. Your cpu voltage may a little high. Is your oc stable? The e8400 does oc quite well. I just checked and found out that max temps for the 8400 are 72C. What are you using to check the temps?
Trying to rotate the cooler is a last resort for me because I will have to take the MB apart again....
The voltage is surprisingly low.... I don't have the exact figures at hand because I'm currently at work. I will post them when I get back.
I am using Everest, Realtemp and Coretemp.... all of them are giving me the same results...
My OC'd system is very stable for the moment, however, I turned it down yesterday until I can get some answers on the matter....
