Cpu Temp Showing 127c....

[Tim Still]

Ive been doing some research, and i figure the sensor on the cpu is broken. It is reading 127c and i know that cannot be possibly right. It stays at 127c and then will go down to 55c for a couple seconds and then right back to 127c (as you can see in the graph). The fan also fluctuates like this and it is VERY annoying.

I have felt my heatsink and it isnt hot to the touch..

What do you think is the problem here?

Have you tried different monitoring software?

 

[Tim Still]

ive looked in bios, speedfan and this one. they all show 127...

i think the temperature is okay.. i just wish there was a way to lower the rpms on this fan...

as the cpu is a few years old the thermal paste under the cpu fan may have dried out. call your local best buys or computer stores a lot of them sell the repaste kits with the cleaning wiped and paste in them. all you need if you dont have a lot of funds is pick up the paste and use 90 percent rubbing alcohol on a cloth to clean the cpu.

It is an incorrect reading or bad sensor.

Thanks all for your suggestions. basically id like to know if my fan speed can be set without relying on the temp sensor?

 

[popatim]

cpu fan may be settable in the bios. Systems fans may or may not be there too but you could purchase a fan controller to do the job also. Just be aware that system fans are usually 3 wire and cpu fans are usually 4 wire and PWM which needs a different kind of fan controller.

Of course you could always change your cpu fan to a 3 wire fan...

 

[Tim Still]

the cpu fans show up but there is no way to change the fan speed based on the temp

 

[Tim Still]

like it always just bases speed off of temperature

You have no duty cycle setting for cpu?

 

[Tim Still]

im not sure i understand what ya mean.

 

[popatim]

which motherbd do you have?
The settings probably wont be there for an oem system like HP or Dell...

 

[Karadjgne]

Yeah, kinda all depends on the bios, my old Dell 8400 bios had fan duty cycle settings, my daughters newer Sony vaio doesn't.

I have the M5A88-v Evo

I was making sure the pins were all connected and noticed this doesnt look good at all. so much dust. do you think this could be the problem? i tried cleaning it up a bit with toothpick (no duster atm) and i started my cpu and its running 1000rpms slower fan but still shows 127c temp

 

[Karadjgne]

When cleaning my pc, I use an old, soft bristle 1" paintbrush to stir up the dust, an artists paintbrush to get between fan blades and the hose on my van about 3-5" away, to remove the dust. Beats the hell out of a can of compressed air, and costs nothing.

 

[Tim Still]

Well im kindve scared to keep running this cpu. the fan keeps throttling from 5000rpms and then it goes idle for 1-3 secs... was playing a game and the screen started glitching out.. not sure what i should do

 

[Karadjgne]

RMA the cpu, may still be under warranty.

 

[skit75]

Before you RMA a CPU, you should clean that heatsink out. It is completely caked by the look of it. You gotta remove the fan and get the gunk out from in between the cooling fins of the heatsink.

 

[Karadjgne]

What gets me stumped is that that phenom ii has a 90°C shutdown and the Silicon the chip is made from is rated at only 97°C. If in fact the cpu is reaching over this limit, it should have shutdown immediately to prevent damage, or, the cpu has already broached the 97° Silicon limit and so basically is fried, which would explain the 127°C reading.

Unscrew just the fan, clean out the dust from the heatsink, put the fan back on and pray you haven't cooked the cpu. If temp doesn't change drastically, as in you should be seeing idle temps @40ish, load temps 50ish, then RMA the cpu or buy a new one, because the one you have now is cooked.

 

[skit75]

I don't think it could ever reach that temp to read it. That is well beyond most silicon limits. The sensor has to be fried or at the very least is being misinterpreted or skewed to produce that number. He certainly wouldn't be able to boot to a desktop and or run any bench-marking applications if that number was real.

 

[Karadjgne]

Exactly. And if the sensor is bad, you really don't want to keep the cpu. I'd RMA it, Pronto.

I thought the sensor(s) were all on the motherboard, not the CPU. Is that an AMD thing?

 

[Karadjgne]

Nope. There are several sensor locations. Core temps come from a sensor strip inside the cpu on each core, package temp is on the mobo by the cpu, and another that's under the cpu, etc. It's important that each core temp is independent of motherboard dependability because the cpu manufacturer can in no way guarantee the reliability of another company's products.

 

[Tim Still]

Computers been running fine. i have confirmed from my brother (previous owner) that the temp sensor is messed up. he has had it showing 127c for a year now so that is impossible its not done for. Also i was trying to remove the fan, but im not exactly sure how.

Anyone mind explaining?
