Question

CPU, GPU and NB overheating with no apparent reason?

by RFMASTER / October 22, 2011 9:21 AM PDT

I have already tried cleaning every heat sink, every fan (they spin freely and really fast), reapplying thermal paste (no more than a rice size amount), even taking the motherboard out of the case and just connecting the motherboard (with Video Card, Processor and RAM sticks on) to the PSU and the HD where my OS is installed. and still overheating!!!

The idle temps according to Speed Fan are:
CPU 68 C (156 F) on flame
GPU 53 C (127 F) on flame
MB 34 C (93 F) blue arrow down
Core 44 C (111 F) red arrow up
HD1 35 C (95 F) blue arrow down
Temp1 68 C (156 F) on flame
Temp2 34 C (93 F) blue arrow down
Temp3 25 C (77 F) blue arrow down
CPU FAN 2986 RPM
FAN1 2986 RPM
Vcore1 1.15 V
Vcore2 3.15 V
+3.3V 0.00V
+5V 5.00V
+12V 11.78V
-12V -16.97V
-5V -8.78V
+5V 6.85V
Vbat 3.26V
Vcore 1.15V

I also tried measuring the temps with ASUS Probe II and the same result, BIOS also shows the same result.
My motherboard is an ASUS M3A, a AMD Phenom X4 9550 (2.2 GHz per core) processor with out-of-the-box Heat Sink and cooler, two 2 Gb DDR2 800MHz Kingston RAM stick, and XFX PCIe nVidia GeForce 8600 GT 512 DDR2. PSU is a generic 450W unit.

Any suggestion? HELP

68 C is not overheating?
by R. Proffitt Forum moderator / October 22, 2011 9:30 AM PDT

I can't find a temp that is out of reason.

According to AMD it is

I read in the official AMD site that the MAXIMUM working temperature for this processor is 70 C, my cpu gets that hot even being outside its case, with no working load, with a perfectly working fan, clean heatsink and new thermal paste. Its temperature under those conditions should be half that.

Not only that...

It reaches easily 71 C if the room temperature gets so much as 28 C, and even restarts itself with no warning...

Try installing AMD Cool/Quiet driver to see if it helps. No? Then dump it and move on. Latest AM3 CPUs will fit on the mobo so it's an easy upgrade.
1st gen Phenom quad was built using 65nm and with AMD not knowing how to turn off unused caches, it's a natural space heater. AM3 uses 45nm.

Those restarts are common with home brew machines which is sad. I'd make this a warranty issue and check that other reply. While I find we have to change motherboard or RAM in such machines, imagine the person that built their own machine and has to deal with this. It's never pretty.

I don't buy other processor just because I can't just yet, and even if I could I wouldn't dare to put it on my motherboard and connect it to my PSU if I'm not sure where the problem is... and I don't even bother about the warranty because It's over already... my PC is 3 years old and I didn't assemble the pc, I bought it from a Store but I'm more than qualified to assamble one if I wanted... I just need help with this problem

Then back to the store.

That's where your warranty is at and if they created a problem they get to fix it.

As I noted, it's often fixed by changing board, CPU or RAM.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
