System crash (overheating).

it's done.

bought the computer case which I've linked above.

re-built the whole system...

...now I need to crush the ice from the harddisks *lol* :D :D



the system was built by a pc-store. they've done a very good job but I think the case was too small and there wasn't enough
space so that the air could circulate. Now I've got lots of space, some very very very big fans and suprisingly it's very silent.

hardware monitor:
CPU 20 degree (68F)
system 30 degree (86F)
core 0: 28 degree (82F)
core 1: 28 degree (82F)
core 2: 28 degree (82F)
core 3: 28 degree (82F)
gpu core: 50 degree (122F)
hdd: 22 degree (72F)

let's play some WoW and test the system.

Good case aint it =D,

ok awesome. glad you got more room and more airflow! lets hope it doesnt overheat again, otherwise we're going to have to trouble shoot it more.

hmmm

ok, the case is cold
the cpu seems to be cold
the cores are warm but not hot (~40 - 50 degree)

but the gpu of my 8800 GTX XXX is still hot as hell.

What are your gpu temperatures of your 8x00 series
when you got 5x wow running and clearing an instance?

my temperature went from 50 degree to 70 degree very quick
and I know that my pc usually crashed when my gpu reaches the 80 degree mark.


//Edit:
looks like gpu temperatures of 70-90 degrees are ok.
the fan-control of the gfx-card activates the next level at 85 degrees.

so I need to check the RAM and the power supply this evening :(

The GPU temps did not seem that bad it certainly could have been better. At least you got a better case out of it. A lot of folks just slam fans in a case without thinking of air flow I see you mentioned that you had exhaust fans only of course this is bad. I will plan my air flow out ahead of time I usually like to suck air in at the bottom and vent out the top, heat rises so why not use it to your advantage.

I would check your video drivers as well and start unplugging hardware after that.

good luck!

Q6600 temps up to 71c are acceptable for long term use. 8800 temps over 80c are a bit worrisome. Most overclockers for the 8800 say to keep it under 80c. One thing you can try is downloading EVGA precision (It will work with your 8800 GTX) and force set the fan to 100% and see if that helps with the issue. IF it does then you can confidently say that your GPU was the problem. I would then go about playing with the fan speed using EVGA precision to find the sweet spot that keeps you cool enough. You really don't want to force the fan to run at 100% (Super Loud) when it only needs something like 60%. You can then either flash your video card bios to force keep the fan at that speed or just have EVGA precision apply those settings on startup (This is what I do).

Another option is an aftermarket GPU Cooler to keep your 8800 GTX cool. I can personally vouch for the Thermaltake DUORB.

If you have great case airflow now then you could also go with the Arctic AccelS1 which is fanless (You can attach a 120mm fan to it if you need to, most don't)

thx for all the input guys, it really helped me a lot.

for the temperature of the 8800 GTX XXX:
the gfx-card is overclocked by the manufacturer. so the temperature is higher than on the "basic" cards.

as mentioned in the following link
http://www.computerbase.de/artikel/h...e_8800_gtx/30/
the idle temperature of the chip is ~60 degrees.
with full load it is 81 degrees.

several overclockers kicked the card over 100 degrees before they had gfx errors and the card crashed.

so my temperature seems to be ok and I've checked other things.


hopefully I've found the problem - the store which built the PC overclocked the RAM a little bit to get more performance.
due to the fact that I kick the system to its limit I think the ram has broken down and so the system crashed.

I've slowed down the ram a little bit and cleared one instance without any problems although my gpu temperature
reached 78 degrees sometimes.

I hope it works now.

I'll keep you updated.

meanwhile... a big thx to this community =)

I remember, The old 6600gt used to idle around 70-80 and would hit 100+ in game :P
But nvidia did say hose cards ran quite hot

hehe..

played half of the weekend - no crashes *g*

GPU ~ 72-75
CPZ ~ 45
Cores ~ 52
Harddisks ~20

excellent case!


bought myself a 30 GB Solid State Disk (SSD) on Friday,
installed WoW on it and symlinked the data and interface folders.

yam yam..

Grats on getting the issue resolved. Case airflow is very important to keeping a system cool. :thumbsup:

*meep* *meep*

;( ;( ;(

Went to Zul Aman yesterday - second boss, fast fight, lots of animations,
monitors (both) turned off (standby mode), Teamspeak was still working
(for about 3-5 seconds) then my whole PC rebooted. :cursing: :cursing: :cursing:

Any ideas?

RAM?
Power?
GFX Card?



PS:
I'll do a complete RAM check this evening after I've installed Windows 7.
