I was able to re-install bios A10 (it appeared to include a couple things my already installed version didn't :emotion-18:).
Anyway, tried running a number of things to keep the processor at 100% for a few hours. Looks like the fan speeds now do change and the maximum CPU temperature I was able to get (and only briefly) was 72C. It primarily sat in the mid to high 60s with fan speeds varying between ~1000-1500 rpm as required to keep it there.
I has nothing to do with the CPU paste nor the fans, although a large heat sink will clearly help. The issue is that the BIOS is simply unable or unwilling to up the fan speed when it gets hot. We've no updated the BIOS in a while but I doubt Dell have done anything. They seem completely uninterested. The only viable option is putting in a separate fan controller that you can buy. We've not tried this yet. For now the machines are locked in a small room, so the noise doesn't matter.
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:
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.
I'd agree - same problem, same response from Dell.
However, I have found that my CPU temps stay below 80C now that the second heat sink has been replaced (perhaps it was a slightly less lumpy copper surface on it?!), so I don't think we'll go down the route of court action just yet.
However, this seems to think the maximum allowable temperature for my CPU is ~95C, so never actually throws an error i.e. my machine passes all tests. I think this is frustrating, but it's taken up too much of my time to look into already (small company, no IT department!). If/when the machine burns up I've kept logs of all discussions and 'resolutions' from conversations and repairs carried out by Dell. They have simply told me that those machine temperatures are fine :emotion-8:
This note is really just additional note for others reading this.
Dell have asked us to strip back the first machine to a single CPU. We then ran tests and achieved a peak temperature over 15 minutes of 84C. This is my response to them:
---
Dear X
Results from the our first computer with one CPU. Note peaks temperatures of 84C.
Some observations:
- We conducted this test with an ambient room temperature of 30C (representing what we think will be peak temperatures in the summer).
- The case fans do increase in speed in response to increasing temperatures internally - so the memory in particular doesn't seem to get excessively warm. So that part of the system is working as I would expect. And naturally with a single CPU the case fans are capable of providing a substantial part of the cool need by the CPU.
- However the CPU fans have not noticeable change in fan speed throughout our tests. (And yes the case was closed during the temperature testing). And this is clearly wrong. The easiest and quietest way to cool the system is to increase the CPU fan speed, but their stuck on what ever setting they have from the start.
- With the temperatures shown (in the picture below) the CPU fan should have gone ballistic - it isn't. Please note the limit set by Intel is 82C.
As such, when we have two CPUs in series, the second CPU gets the heat from the first CPU, and temperatures head into the 90s. The problem in MHO is that the BIOS software that control of the CPU fans is faulty - most likely the temperature settings it is responds to are off.
Very good response, I'd be keen to see what they say as I can also replicate the same results with my machine (temperatures, case fan response and no CPU fan response).
Please keep posting information here regarding your progress, if it starts to look promising (or you think another user reporting the same issue would help) then I can also contact them.
I would contract them and mention my case number: #888345483. I'm sure they'll say they can not comment on another persons case, but IF they are smart, then they'll link them together.

Zacktown, did you find a solution. We have exactly the same problem
