Thanks BatOutofDell,

I thought that too, so I checked the temperatures on the Dell diagnostics right after running the system pretty hard.  They were still at 70C+ :emotion-43:

I'll try to look at some other programs, but essentially this a new system as delivered from Dell...shouldn't it just work?! :emotion-4:

Hey there AWMACKAY,

Seems like a problem with your speedfan and CPUID programmes to me. Temperatures of 90C are pretty much unheard of in the T7600. I'd suggest investing in a decent programme (I'd recommend the Windfire T340) for checking the fan speed and temp, splash out, more than worth it :emotion-4:

Get back to me if you check it with a decent platform and it's still giving you those figures, I'd be really interested to find out how you get on,

Ok - ran some stuff over night and the temperature of CPU1 (which sits behind CPU0 so gets hotter) hit 84C...nothing from the fans at all.  I guess I'll contact Dell technical support, I'm sure that will be a pleasant experience :emotion-6:

I know this is an old thread, but same here.  Brand new t7600 dual procs.  Idle is approximately 50 C for the CPU closest to the rear.  The one in the center idles at 60 C.  3d renders take cpu 2 to 90 C easy.  The fan for CPU 2 never speeds up.  Any ideas are greatly appreciated.

On a side note,  my last dell computer was 6 years ago.   Easy transaction and great people.  Now, it has all changed.  You get to speak to very nice people all over the globe that have no idea what you are talking about.  Why are they all named marvin? 

@Zacktown - after speaking to Dell support, they suggested replacing one of the CPU fans (the one for the second CPU since it gets warmer).  After the replacement, the temperatures are a little cooler (perhaps max of 75C instead of ~90).

I couldn't get much help on when the fans were supposed to kick-in.  Having read the the intel processor documentation I still couldn't make sense of it (nor should I have to since I bought the system from Dell!).

We've recently bought two Dell T7610 (both with the later A03 bios). The problem persists and when we upgraded one with a second core we've seen temperatures in the 90C (my colleague claims 95C). With a single CPU we get maximum temperatures of 81C. There is slightly more movement from the CPU fans in both cases, but its barely noticeable. Intel mean while state that the maximum CPU temperature is 82C: http://ark.intel.com/products/75277

The only thing we are doing that might be slightly different is running Ubuntu 12.05 LTS rather than Windows. But last I checked it wasn't the operating systems responsibility to make sure your computer didn't melt. The only solution at present is to set the fans in the Bios to the medium setting, at which point all the fans in the whole machine rev up and you have a very noisy neighbour, but even under heavy loads we don't see temperatures above 60C - about right? So basically this is a fault with the programming of the Bios, or how the Bios detects temperature. Given we have the identical problem with both machine, then I'm 100% confident this is a design flaw. Unless Dell respond appropriately over the week then the second machine (which we've just received) is definitely going back; and I'll try for a refund on the first. In either eventuality  I report back that this is fixed. Something else to add to the mix. The Dell Heatsinks are cheap. If you look at any other heatsink, the copper bottom where it connects onto the CPUs have a flat mirror finish. The copper pipes on the Dells look like they've been hammered out by kid on a street corner and are filled with pits and bumps. Fundamentally this isn't the problem, but it certainly doesn't help.

I think you and I are on exactly the same page. Dell pro technical support is virtually useless. The technical guys their 'say' they are looking into issues, and they seem on the phone to be taking things seriously. But if you miss their one attempt to call you back, then they close out the issue as fixed. They don't follow up later, they don't respond to emails, and at the very least I would expect a courtesy call a week later to make sure everything is as it should be. And when I ask how to return the machines - nothing.

So as I said above, about a year ago I got the fan replaced by DELL for CPU1 (the one behind CPU0, so it gets hotter).  I can't say it's made a huge difference to be honest.  I'm still running Windows 7 64 bit and I've just updated to the most recent bios (version A10) for the machine.

The maximum CPU case temperature for my processor is ~77C (http://ark.intel.com/products/64594), doing a test using an intel CPU program I can easily push the temperatures up to 80C+ (not waited long enough to check how high it goes) with no noticeable increase in either CPU fan speed (using HWiNFO64 to check temperatures and speeds, although I've also quickly gone into the bios to check too).  There is a slight change in the chassis fan speeds, but again not by much and it doesn't seem to do anything to halt the increase in CPU temperatures.

I have tried contacting tech support and I found them to be not very helpful - I'm really surprised it's allowed to run so hot given the limits of the CPU.  I can just imagine my CPUs failing in a year or so when they are out of warranty!

Note: using HWiNFO64 I can set custom fan speed settings based on CPU temperatures, but I don't see why I should have to do this and I also don't want to override what is presumably a safe default setting.
