Mobo over 80C!

Defcon5 · 11 Mar 2006 at 23:05

After a while playing bf2 i got a bsod, so i restarted and loaded speedfan to chech cpu temp but everything was fine

Looked at my temp probe and one of the heatsinks on my mobo is over 80 degrees (the temp probe only goes up to 80 so it could well be over 100.

All my voltages are low (1.44v 2.8v for cpu and ram) so i was wondering what copuld be causing this?

Could it be the psu throwing too much at the voltage regulators?

Its a ultra d btw qand the sink is the one on the top right

What CPU?

Try touching it to see if it's really that hot. Mobo sensors are normally way off/broken. Since I've got better airflow in my case my temps have gone down to -40, so I just ignore it totally. Seeing as it's a DFI it shouldn't be becoming unstable due to that sort of overclocking.

Venice 3000 @ 2600

Its a physical temp sensor, if i put it on my hand it goes to about 25 ish so it works

If it's the PWMIC then I've had mine up over 90C without any problems.

Dual core are particularly hard on them.

Is that a small rectangular one on the top right of the board?

By the memory slots? Yeah.

On my A8N-SLI I've actually had it off the calibrated scale of the sensor (127C+) when stress testing a FX60.

Nicley done!

Least i cant smell burning like with my A7N8XE!

PWMIC are good for 100c

wow talk about thermal inefficiency >.>

yeah I have read this as well, hehe so at what temp does metal actually melt/boil?

the silicon or metal isn't a problem but I can imagine the PCB around the chip is also very hot.

The indicated temp on my DFI mobo is usually ~40C, maximum ~50C but I have a quiet 80mm fan blowing over a corner of the memory, the PWMIC chip and the MOSFET's

putting a fan over the problomatic area to increase air flow will solve these general overheating problems. but it shouldnt cause u too much of a problem as long as the case is well ventilated.

OCZ coper ram sink and a fan job's a gooden, use some AS% pastes and epoxy mixed togther to fit the ramsink
