Overheating-Is a new case in question?

I'll give you a quick run-down of my situation:

I bought as computer from Mesh about 2 years ago and have had nothing ut trouble with it. I've even been extorted out of several hundred pounds (the lesson: avoid Mesh like the plague). I'm currently in the process of getting all my money back (hopefully ending soon).

Mesh have actually blatantly lied to me about all sorts of hardware failure I've had over the last two years, and I've lately narrowed it down to heat.

I had an 8800gtx and it was hitting 80-90c under strain and sat at about 60c idle. Not good at all. After having it with crashes that collerated with the intensity of the task and the time the computer was used (plus I suspected failing hardware) I got myself a GTx260 from OcUK. Fabulous so far. It runs about 30c cooler than the 8800. The only problem is I still have signs of overheating (mainly stuttering framerates and graphical glitches), but not to the extent the previous card had.

I noticed on both the 8800 and the 260 that it usually takes several minutes for it to cool down to its idel temperature, and sometimes it sticks 10 degrees above.

The case Mesh have provided has two front case fans and a 500w PSU. It's incredibly cramped in there (it was a miriacle they got the 8800 in there) and the CPU heatsink is very close to the PSU, which I understand can lead to overheating.

I've got my eyes on an Antec 900 case. Does it sound like I should get a case that isn't like a pressure cooker?

[Edit] Also notable- there doesn't appear to be any difference in temperature between SmartFan and all fans set to 100% manually.

After about an hour of use this is what SpeedFan reads:

GPU: 46c
System: -65c
CPU: 32
AUX: 35c
Core 0: 29c
Core 1: 25c

Those temps look pretty reasonable to me, and 80 isn't high for a GPU.

In fact, I'd say those temps look low - after an hour of use my laptop is running at more like 65 all round.

LOL thats a laptop, they do tend to run hot and 65c alround isnt that bad I wish my GPUs ran at that all the time

65c system temp :eek: thats hot, and my system is at like 50c and its in a big armor

I wouldn't get the antec 900 through, becasue the GTX260 is quite a long card and you may have problems fitting that in :rolleyes:
 
I've just ran a wee experiment. I turned the chassis fan off, and the mobo and aux fans to 50% (the lowest they can go). By the looks of things it runs an odd degree higher than with everything full blast and the rate at which the temp drops after an intense session is practically the same as before.

Would this be a sign that the heat isn't actually getting pumped out of the computer? The exhaust vent has always seemed incredibly weak.

Indeed. Seems to be the case with my current case. Because of the way Mesh wired the computer (i.e., pants) you have to pull a load of wires away and navigate the card in :(

What would you suggest as a decent case that could fit a 260gtx without too much hassle?
 
90c is standard practice on an 8800gtx with a standard cooler - its nothing to worry about. at all.

the rest of the temps are well inside the margins. that system temp isnt 60c either if its actually reporting minus 60c - its not a real temp at all. if it were 60c you'd burn your hand just putting it inside the case. come on guys, think about it;)

I was more pointing it out for juxtaposition - but you're right.

Is that sytem temp actually at 65c? I just assumed it was an erroneous temp since it's negative...

take a few pics of the case.

whats the, mobo & cpu & what brand is the psu as that might be the problem

I think the PSU is HEC. It certianly doesnt look like anything spectacular.

Here's a bog standard pic.

I can't seem to tell whether SpeedFan is working or not. I get a feeling it's telling me my computer is running at minus 65c :/
 
Sort out the mess of wires, they're hindering airflow. Stick a proper heatink onto that cpu, too, then see how it looks.

That really is just a tangle of wires.

I'd ignore the -65, I'd suggest that it's just not connected to anything.

Hmmm. Had a feeling the wires would be causing some problems. Only problem is they've got these iritating cable ties that you can't undo without cutting it off.

Yeah, I think the -65 is a bit strange. It's kind of annoying because it's the measurement I actually want to check.

It might be an nvidia driver issue (seeing how notoriously crap some of there drivers are), but there doesn't seem to be a lot of rucuss about the 260 having problems, and it always seems to correlate with how long the computer has been on, how long its been left and how intensive the tasks are, not to mention I've got the same crashes in both Vista, XP and 7. I always get signs of overheating before it explodes on me, which makes the matter more confusing.

I doubt the psu is causing overheating, but it could be killing components.
Case looks alright to me. Cable ties got to be cut, get all that crap out of the way of the airflow.
Standard intel cooler is pretty nasty. If you like the look of the current case, a sunbeam cpu cooler, and a couple of decent case fans are likely to solve the problem.

Sad to hear of mesh being crap, they were pretty good a few years ago.

You don't know the half of it :(

The case itself is actually very nice looking. Sadly it's door was held on by plastic with the consistency of a mars bar. The front intake fans also happen to be covered up by part of the case apart from a small opening. I wouldnt be surprised if that was a bit of a design flaw.

I've just played Arma for about an hour. It began to glitch up so I took the side of the case off. About half an hour after that I stopped playing and the GPU core was at about 50c (and the difference between Riva and Speedfan is usually 5-10c).

Seeing how the side of the freaking computer's off that ain't too good. The glitching did stop though.
 
The temps are fine though which is pointing me towards the psu as maybe under load its too much as a doubt its a real 500w.

Also I would strongly advise you replace the termal compond on your north & south bridges as i reamber the stuff they used on those boards was crap & you can change the tim on your cpu at the same time which should bring that down a few degrees.

Also as said cut those cables tye & get routing.
 
PSU is my bet, I wouldn't risk the GTX260 with a PSU like that. You could buy a Tagan Power Forge to protect it though.
And lawl, just went on the website and saw an advert for one of their PCs with "Now Even Hotter..." as the main title :D
