I just finished building a pc for my friend using the OCed i5 760 bundle with the titan fenrir cooler. It seems to be getting way too hot, 50-55 idle and it went up to 99 according to both core temp and real temp when I ran burn test. I've tried reseating the heat sink but it didn't make any difference. The weird thing is the cooler doesn't even seem to get particularly warm.

Any help?
 
airflow in the system?

my i7 920 @ 4.0ghz was running at almost 100C under load in my lian li case until I realised there was no intake fan on the case... slammed one in and that went down to 90C. now I've stuck another decent large fan in the front and i'm at 82C under load.
 
It's in a 300 with 1 intake fan on the front but I don't think air flow is the problem. I think the cooler jut isn't up to it or it's a duff one somehow? Gonna have to see if they will take it back and get a different one because it clearly isn't suitable for purpose. I don't understand why they put it with the bundle if it's not gonna work though.
 
I don't mean to be 'that guy' but, the Titan Fenrir gets pretty good reviews! If you believe the tests it is in the upper several percentiles of coolers.

Things that can make it run hot:

Too much voltage on the Vcore - the chip needs juice, but it may be set a little high.
Poor air flow. Intake and exhaust vents needed IMO.

Can you give us some details of the overclock? Board etc...

I run an i5 750 which is currently at 4.218GHz. It idles at 42*C and breeches 75 when pushed with the intel burn test. My cooling solution involves a side 18cm fan, a rear exhaust fan (72CFM) an intake fan on the front (68CFM) and the CPU cooler itself (Arctic Cooling Freezer Pro 7). I am replacing my CPU cooler with the much heftier Fenrir, and I expect all my stats to drop!

What TIM did you use? Akasa makes nice stuff. Make sure you apply it nice and evenly.

I know you did it, but idiot check things - make sure the fan isn't throttled down by the MB. Make sure it is well seated. Check the fan is putting out a good airflow. I believe that fan is around 82CFM. That isn't doddling!!

A hot room influences your results... it may be too simple to have noted.

Well I remember the Vcore was 1.4 is this high for a 760? But I got this pre overclocked from overclockers with the entire point being I wouldn't have to do this stuff my self.

I don't think air flow is a problem. The case has 1x120mm rear exhaust fan and 1x140mm top exhaust fan, both about 3 inches from the cpu cooler and then 1x120mm intake fan at the front. I used mx-3 thermal past to fit the cooler, which I have removed and reapplied every time I've reseated the cooler, to no avail.

My pc (in sig) is in the same room and only hits about 85c Whereas his has been hitting 99 and actually been throttling it's speed as a result. The only thing I can think of is that the cooler isn't good enough or is broken some how.
 
If the heatsink is cool to the touch then the problem lies in measurement of the temperature, or in the contact between processor and heatsink. No other options.

At first I thought this but I've used the blob method of applying the thermal paste and I could see when I removed the heatsink that it had been spread out by firm contact between the cooler and the cpu. As for the programs not reading it right, this seems unlikely as I have used both core temp and real temp. Also the speed of the cpu reported in realtemp lowered when it reached these high temperatures, indicating it is actually getting that hot and throttling the speed to try and compensate.
 
If you take turn the fan off, put your finger on the base of the heatsink then run ibt, does it burn you or still feel cold? I'm wondering if the heatpipes are faulty and you're only touching the top of the heatsink when you say it's cool to the touch
 
Could also be the fan on the cooler. Disable the CPU fan control in the bios so its runs full pelt constantly and see if that makes a difference. If the fan is not good enough or running slow because the bios is telling it to then that can cause high temps.
 
I'm kind of having the same problem with my i5 760 @ 4ghz. Temps on load reach high 80s with 1.3v with the H50. :|

Something really wrong with the heat sink I think? I can touch the bottom of the heat pipes, right where they contact the cpu while running burn test and it takes a minute or two before they even start getting warm. I don't understand what's going on. I can't see anything physically wrong with the cooler.

Why is this one at 1.4v and yours only 1.3? :C
 
Ok, I have no idea whats going on. Is it possible that the proccessor could be faulty and isn't distributing the heat out somehow? I just put my eco coolit on and it wouldnt even boot with the oc overclock. So I put it to stock and booted to windows. Ran intel burn test and it was hitting 95c. The weird thing is, once again, no hot air was beeing blown out from the radiator. On my PC you can feel the air coming out is warm if the proccessor is even 70c let alone 95.

What the hell is going on?
 
thats not the problem. The problem is the heat isn't even getting to the cooler. The fans are on max (two akasa vipers in push pull) and It's cuirrently on stock so it's like 1.05 vcore and it's still hitting 95c in burn test. What the fup is going on.
 
Motherboard not reading socket temps correctly.
CPU providing wrong data.

It all could be fine but requires checking to find the culprit, return to OC?
 
It is conceivable that the solder between chip and ihs is missing, but incorrect temperature readings are far more likely.

Either rma it, expecting to be told it's user error by a barely literate moron or:

Reset to stock
Install known working heatsink
Run ibt, watching temps. It should switch off around 100.
If it just keeps getting hotter without crashing, suggests temp reading error.

Or:

take the heatsink off, put your finger in its place. Switch it on. It should burn you severely then switch off. If it starts booting, then turns off without burning you, its a problem with the cpu assembly (or my reasoning).

That last option is a bit brutal. Testing a cpu that is thought faulty while requiring that it throttles correctly requires a touch of insanity. May also void warranty.

I'm pretty sure it's something to do with the temp sensor. The reading I get seem to be totally irratic. Like sometimes I boot up and im gettint 17c idle and 99c underload and then sometimes I'm getting believeable temps like 40 idle and 70 load. Should I still send it back?
