i7 920 bundle: temps too high?

[dna598]

I got a I7 920 bundle @3.6ghz (requested speed, bundle advertised @4ghz)

I requested this speed so as not to fry my system too much over time/keep system quiet.(recommended by PeteG)


However I am getting idle temperatures of around 53 to 60c across the cores (using coretemp). As far as I am aware from reading things on the web, this is a fair bit higher than usual.

I apprehensivly ran prime95 for a matter of seconds ( not an "overclocker" myself) and watched temperatures jump into the 90's.

I am concerend at these temperatures, as I was under the impression the Megahelems would provide more than adequate cooling, and idle at much lower temps. I have read for example, that it shouldnt be more than 70c max, and idle at around 40c oc'd.

Aswell as the (1) apache fan on the cpu cooler, I have installed 4 case fans.

Please advise

regards

doesn't sound right, maybe the cooler has come loose or unseated? start checking there and that the cpu fan is plugged in and spinning too.

Can you supply the invoice number please?

Thank you.

DNA598,

Please ensure that all the fans in the Fractal Design chassis are connected up and functioning as it does appear that the CPU speeds are too high, and as rabbid has stated, sometimes the CPU cooler can become loose when transported so I would double check this as well to be safe.

If you've tried this and the temperatures are still quite high, if you let us know we can then have a quick check over and see if there are any other things which could be causing this issue.

Hi,

It was about 40 idle and around 80/82 here under Prime. You won't acturly hit 80 - 85 in the real world in very many situations so if it's holding around that point then we consider it a pass. If it's running higher than that, I'd certainly check the heatsink as it does sound like it's come loose in transit.

Pete.

Thanks for getting back to me,

When I put it together I didnt notice anything loose, But i ll check again when its cooled down. All the fans are running.
In between posting, I phoned in and got through to Sanjay I believe. I asked him what idle temperature he would expect for this type of build. He said 60c. This was before I mentioned my system temp!
So that totally threw me, as you confirm that 60c is in fact, too high.

Keep you posted.


Regards

Ok I checked and nothing was lose. But i gave it a tighten anyway.
I also took one of the modu vent panels off the side of the case.

Temperatures are now 44 to 50c across the cores idling. Its better,but still a little higher than id like. I was aware that the thermal performance of the Fractal case could cause issues.

Pete,was it inside the case when you got 40c idle?

Would adding another apache fan doing anything except make more noise? Ive read it can only make about a degree of difference, and perhaps even increase temps(!?).

Not using a stock cooler by any chance are you?

At Scan they have air conditioning so they'll lower idle temps.

[dna598]

Most people seem to be experiencing idle temps of 38-40c, like here

I am getting 50c idle here after taking off one of the vent plates.

I reckon they had the aircon on and the thing tested on a bench outside the case. But i cant be sure as they have not responded.

I have an i7 920 with SpeedStep enabled and it's 39C-46C idle at 2.3ghz and on Prime95 after 5 mins it's 77C-85C load at 3.8ghz 1.31V. i7 920s can run up to 100C without being damaged but personally I wouldn't let it run above 90. This is with a Noctua NH-U12P with 1 Enermax Magma fan on it and 5 other 120mm fans in a NZXT M59.

The idle temps seem a tad high and the load temps certainly are way too high for Prolimatechs. Can you download CPU-Z and check the Core voltage? Is SpeedStep enabled?

[dna598]

This is what im seeing at idle.

[Ulti]

Well the idle temps seem fine but load temps certainly do not, this means that the cooler somehow isn't installed correctly as it can't dissipate the heat fast enough as it reaches 90c in a few seconds as you said.

[dna598]

Pretty sure the tighten helped.

load temps at 75 now, with no jumps to the 90s.

Given the set-up I'd think 75C is acceptable. Your core temp "high" doesn't go above 60 on any of the cores, does this represent multiple sessions, or just the highest temp recorded since the program was last loaded?
