These temps seem high...

[hurtmypony]

I bought a Corsair H80i to cool my new Ivy Bridge i5 3750K. Gigabyte board.

 

I tightened the thumb screws with my finger.

 

Ambient temperature is a consistent 22c.

Everything running at stock.

 

Idle doesn't seem so bad: 25c - 31c

5 minutes in Prime95 and it will shoot up to 71c. It generally stays around there for as long as I have been willing to babysit it - maybe 45 minutes?

 

IBT will send it upwards to 77c.

 

I am using CoreTemp and RealTemp, alternatively, to test. They seem in agreement as far as temp is concerned within a degree or two on all the cores.

 

However, my concern is CorsairLink. There are several discrepancies:

 

1. And I understand the CL temp is a collective temperature of all cores, but there is a dramatic difference in temp reports. While CL might show a peak of 60c, RealTemp and/or CoreTemp show 77c at any moment during the Prime95 or IBT session.

 

2. There's a significant difference in CorsairLink internal reporting - between Intel CPU Temp and H80i Temp. For example, at idle, H80i temp might be 25c, while Intel Temp is 31c. At load, this gap widens to, say, 60c for Intel and 31c for the H80i Temp.

 

#2 suggests the H80i is not seated correctly, doesn't it? I am new to all of this, and just want to make sure I make the right call and take the right action here.

 

I assume, based on other users and the advertising, I should be getting far better than 77c on a stock Ivy Bridge, right?

 

I also read some Gigabyte boards have issue with the H80i, as the caps are too close to the mount, causing a poor seating. Is my GA-Z77x UD5H one of those troubled boards?

Without removing it, my H80i seems like it is at least firmly seated.

 

I am obviously reluctant to remove it unless I absolutely have to, so let me know if that is my only recourse. I have the necessary tools and resources to reapply the thermal paste, if needed. I am just hoping I don't have to do that.

Those temps look pretty good. You have an Ivy Bridge CPU and they are known to run hotter than Sandy Bridge (previous gen).

 

I think what you are observing in Corsair Link s/w is the temp of the H80i PUMP/Coolant itself. That is very different from the CPU temp that the Link s/w displays.

 

I run RealTemp and the temp it shows matches (more or less within a degree C) with the link s/w CPU temp but my H100i temp is way lower. E.g. when my CPU temp is shown as 89degC, the H100i temp is around 36degC.

 

Regarding the mounting brackets, they may be flimsy/loose BEFORE you attach the pump to the CPU. But once you tightened the thumb screws (even just hand tight), the pump should not budge at all.

 

Yes with certain gigabyte boards, you have to watch where you place the pump onto the CPU as the capacitors get in the way. But it should be pretty visible to the eye when you place the pump on the CPU...just look around all four sides. I had that problem as I was not looking when I place pump onto the CPU.

Hi there,

 

I installed by H80i last night, my idle temps are 40 (too high) on stock, with ambient temp around 20celcius. When I run P95 for about 5 seconds, my i5-3570k hits 90-100c.

 

I have to quickly stop. I believe it's seated properly also, I think these H80i's are just messy and I'm afraid they will be a waste, I hope not.

 

This is my second h80i in a week, so im going to reseat it this weekend, but if nothing changes I'm going to see if it's the unit.

you can have a nominal load 5-10% and get 40c temps but your load temp is too high,check the seating of the old tim,it will show you how well the block is seated on the cpu,reapply tim and check load temps.
