so i took the plunge and picked myself up a corsair h70 along with innovation diamond 7 thermal compound.
everything is at stock speeds on my system, and i'm just wondering if these temps are decent?
38-40 idling
ambient 24
prime95 68-70
i came from a TRUE, and so far it hasn't impressed me one bit. those were the types of temps i was getting with the TRUE
did i do something wrong?
i replaced the two corsair fans with noctua p12's, could that be it? they're made to be silent, not push tons of air.
also what is the proper way to "burn in" the TIM?
i'm reading 1-2 hour cycles of prime95+cooldown
does cooldown mean turn off the system? or does it mean no load.
thanks!

those look like fine temps. the H50 & H70 are a bit weird. their fans are loud but the system is considered silent because its water cooled.... :heink:  I find them both rather gimmicky

well i was expecting atleast better than the TRUE which underperformed for me based on other reviews
how long do i burn in with heat and cooldown by turning it off?

Those temps seem a little high for the ambient temperature. I'm running a 980x oced at 4Ghz with 1.35vcore. Running 30c idle and 68c full load in a 26c ambient room. The only thing i can think of is which way did you mount your fans? The kit states to pull from the outside. However if you don't want to be putting warmer air into your case from the radiator and you have room for fans in the top of your case you could set those to pull air in and then keep the H70 on exhaust.

i have the p183, i have a front intake 120, and a top 120 exhaust, and the h70 is in pull/push config as the exhaust.

Try turning that top fan around to pull air into the case. With cooler air to draw from your CPU temps should come down some.

i guess i'll just try diff fan arrangements. maybe i just need time to burn in the thermal grease before i see drops.

Just to make sure its understood. The temps you're currently getting are perfectly acceptable. Though it is my opinion that you should be able to realize better results. Nice choice on fans btw, the fans that come with it are a little loud for the CFM you get out of them.

Also, to expand on the whole fan thing. The specs for the kit state that the fans push something around 50-60cfm. So what you picked is perfectly fine. I'm using the Scythe SFF21F which pushes a little more, but I've noticed no real gains over the stock fans, just more bearable noise levels.

Um, yeah, nice thick rad with high FPI likes tons of air

does it matter where the pump goes exactly?
the word "corsair" is not horizontal, it's actually vertical.
i assumed it shouldn't have mattered...but i read a review/installation that says you should put it so corsair is horizontal.

Shouldn't have a significant effect, as long as you're not hearing any cavitation.

thanks, i'm gonna try two antec tri-cool fans with switches on them and see if i see any noticeable improvements after a little more burn in time.

i have those fans and they are fine fans but its not the fans. as stated before, the product is just not that good.

FYI, most fans at the same RPM move the exact same amount of air despite what the package may say. Most brands, like antec, don't even make fans. much like GPU, PSU & RAM, there are only a handful of suppliers and ton of brands.

honestly i can't say they're performing poorly.
i had a TRUE before this, and prime95 was in the low 70s quickly.
i might just have a hot cpu for all i know.
it's been running for 6 hours now and it's holding steady at 63-65.
improving over last night's initial figures.
hopefully a few more hot/cold cycles will do it :D

so i swapped out one noctua on the rad for a tri-cool running on high.
with load it barely breaks 60!
not too shabby i must say.
gonna try two tri cools on rad and inverting the top fan as intake.
very encouraging numbers!
altho it is quite loud, doesn't bother me a whole lot as i can always crank them down.

so after 48 hours of tests/burn in, this is my results.
idle from bootup, 32-36 degrees idle, roughly 24 degrees ambient.
2 hours of prime95, 60-62 degrees.
stock speeds.
are these good temps for a i7 920? if i were to overclock, what temp range should i try to stay in?

I have a i7 930 with a H50 and after prime95 it for hours the hottest I get is 65oC but that is with a 4.0ghz overclock. At stock I think is was getting into the low 50s and my setup is with push-pull exhaust, I would warn against intake as for me it massively increased my case temp

Yes, I have i7 920 Oc to 3.4 idle is 40C at 22C ambient, prime95 after 1hour i got 79C hotest reported, but when in real life all 4 cores will be working at 100%. I using ZALMAN CPNS 9900ALED.

I had Corsair H70 for about 3 hours. Only 2C degrees different between this and Zalman Cpns 9900ALED.The fans noise was terrible, and no PWM control fan only 2000rpm or 1600rpm.

i think the thermal grease is starting to work lol.
idle is 29-33, prime95 is 58-60.
very happy so far!
