My computer is running way to hot and i cant figure out why. i have a good fan set up that has worked very well for my in the past, so i dont think thats the problem. right now, while my computer is almost idle my cpu is running at 170f on a stock heat sink. i have a temp monitor on the ouside of my computer and that says the temp is 120f. i have the sensor for the case temp placed right between the fins on my heatsink. so there is over a 50 degree difference between the cpu and the aimbient air. i know my heatsink is seated well cause it get almost to hot to touch, so its definatly pulling heat from the cpu. my first thoughts were get a better heatsink and fan, but ifigured that not really the problem, it may take away more heat but why is all that heat there. riight now its very irratatiing because it get so hot my computer slows way down. any one have any ideas?


oh yeah its a amd 2700 on a gigabyte ga 7s748

Are you sure those snesors are working properly, 50 degrees is a hell of a difference.

If your using software to control your fans etc then make sure they are set to the correct speed.

yeah the sensors im guessing are working cause when the cpu temps rise my computer dramaticly slows down. and like i said before my heatsink alone gets to hot to touch, so i know the cpu's die temp has to by up there. and i my case sensor changes depending on where i put it.. i cant confirm that there 100% accurate but im assuming there pretty close. and all my fans are running full forced.

Is it just your cpu that is running hot? Or is the the chipset and videocard, etc running hot as well?

170! That's cookin'! Check your task manager, is you computer's cpu running at full load constantly? Maybe you have some viruses/spyware that's goofing with your cpu usage.

btw- Does your BIOS have temperature monitoring? If so, see what those temps read. This is a good way to double check which sensors are BS'ing you.

Any idea what the the ambient case temp is? HAve you move anything in the sace latly, it could be an airflow issue, i'm afraid thats the extent of my knowledge someone else may be able to help you more.

the temp thru the bios reads the same. my video card and ram seem to be running at an ok temp.(by touch) but my chipset is very hot. and like i said those are the temps at almost idle.... even after a fresh install of windows. so its definatly not a virus/adware/spyware thing. also so no one askes.. its not over clocked or anything. i dont know if its possible but the only thing i can even it image it might be was like if maybe a resistor or something went and its sending to much power thru the mobo. idk im clueless at this point

hmm... did this start all of a sudden? Or get worse over a decent amount of time?

If the problem came about "over night", then maybe your mobo is going bad. Call you manufacturer and ask / tell them about whats going on with your board.

Here's my two cents........

If you were running fine before and now its running way too hot.
I would keep an eye on that heatsink fan. It may seem look like its spinning fine but it may stop at times or not spin fast enough to remove the heat the cpu is generating.

BTW: Are you overclocking it? If so put it back to stock and then check your temps. When overclocking a aftermarket cpu cooler is a must. The stock coolers cant handle it.

Another thing........
The sensor isnt going to display the correct temp unless its between the cpu and heatsink. Otherwise there's gonna be a big difference in temperature due to air inside the case isnt going to be as hot as under the heatsink.

I may hate to say it but, you might be looking for a new cpu cooler. Those temps are way too high.

I'll take my eggs over easy.....

hmmmm try this....
Leave the side panel off and direct a house fan to blow directly into the case. Does your temps drop and if so how much?

my cpu fan is always about 4000 rpms according to the sensor and it look like its running fine. i know heatsink is making good contact becuase the heat sink gets to hot to touch, as i said. also i said before i am not overclocking. and i know the sensor isnt reading the cpu temp. its a case temp fan but instead the ambient air its between the fins in the heatsink.i dont know what the case temp is but its far less then the 130 the heat sink is at. so it has to be even more of a diffence.. also i have the motherboard sensor under the cpu

also this problem has progressivly gotten worse

If it keeps getting worse, then I'd consider contacting the manufacturer and see what they have to say about it. Like I said before, your mobo might be going bad. Replace it or RMA that thing before it blows up and takes other hardware with it.

If the heatsink is hot to the touch, that means it's making good contact with the CPU, but it being overloaded by it. The hot air is just sitting there with nothing to move it away, and a cascading effect occurs with the temps. I would recommend setting up a fan on the intake side of the case, but the the CPU, so that it'll blow air off of the CPU and into the exhaust fan of your case. if i'm not mistaken, 170*F is close to 80*C (where's a conversion calc when you need it), which is wayyyy too hot. In fact, that's so hot that the sensor is probably wrong! Regardless, I would try setting up a fan like I described and than let us know what happens.

It's a false temperature reading. A64's shut off at 70 degrees if I'm not mistaken. You board is also known for reporting incorrect cpu temperatures.

Get the latestest bios.

i have a good fan set up that has proven its self to my many times n the past with other hardware. so i know that there itsnt any hot air in my machine. or atleast none lingering. also 80C might not be completely accurate but like i said its to hot to touch and when i gets up there sometimes even to 85c i can clearly see a proformance drop. also its not a a64

Could you do us a favor & describe your COMPLETE setup.... including type & brand of coolers, fans,
etc.... That way we can narrow things down, a lot better!

Anyway... I've got multiple systems running here & two of them run faster processors than yours...
their heatsinks obly feel slightly warm to the touch.... definately not hot at all.... but then again these
are BIG Zalman/Scythe heatsinks....

TDR

try a fresh layer of as5.

a64 or not your board is known to have temp reporting issues and the cut off temp will still be around the 70 mark for the cpu.

If your heatsink is too hot to the touch then it's correctly transfering heat, it's just not sufficient for the job. This means you need a new heatsink.

I strongly advise you flash your bios and do a few power cycles / reseating etc etc to get some real temperature readings.

Froom boot do your temps shoot straight to a certain figure or do they increase from say 20 degrees?

Please state what temps you seeing from bios after the pc's been off for say 15 mins.

im running
amd 2700 with stock heat sink an fan
ga 7s748
2 maxtor hd
old cd rom and rw
some old 256 i think pc2700
radeon 7500
and all my fans are unincom

hes a layout




would artic silver really make much of a difference.. its transfering heat well. also i know a better heat sink would bring down the temp but is that really the problem. i dont think that the cpu should ever be running the hot. so im worried if i get a new heatsink and it lower the temp say by even 20c its still gonna be running hot and could still do damage.. and even if my mobo sensors are wrong if the heatsink is still to hot to touch it has to be close to 140f. and that what my case temp is reading wich is placed inside the fins if the heatsink. so if hte the temp of my heatsink the cpu's temp has got to up there regardless if my mobo sensors are wrong. will try to update my bios soon and see what it says. also even from a completely cold boot i never really see it below 70C from the bios.

Let's think logically for a minute.

What is the purpose of a heatsink?
To transfer heat from one object to another.

What is the purpose of a fan?
To disperse the heat from the heatsink

Now taking these two processes into account........

Whats the first thing that comes to mind when the heatsink is getting too hot.

1. The fan isnt doing its job to remove the heat from the heatsink.

So with that in mind............How do we solve the problem?

Replace the fan...........but in this case it's replacing the whole heatsink and fan because they are a set.

Of course other things come into play.......
What's the temperature of the air that's being pushed through the heatsink. The lower the temperature the better the cooling.

So if your telling us that its 140 degrees inside your case. Then you obviously have a cooling problem inside your case. Without a doubt that temperature shouldnt be going much over a 105 degrees. Although that depends on room or ambient temperature. So if your room temperature is say 80 degrees and your case is running at 120. It's obvious that the hot air isnt being expelled from the case.

Let me ask you this......How many fans do you have installed and what direction are they facing. For proper cooling with an atx case. Cool air should be brought into the case from the front and expelled out the back and or out the top of the case.

Are the fans clean and clear of dust bunnies including the heatsink?

I dont know if you took my advice at heart. Which was removing the side cover and try running it with it off. Does it run cooler?
So if you put a house fan next to it does the temperature drop even more.
If it does than its best to say that you have a case cooling problem.

Id certainly would like to see your case setup and see what's going on in there.....Something just isnt right.

Oh, BTW how old is that stock cooler?

I hope this helps you make the right decision.....

rockin'male

Is that the stock cooler that came with your 2700? Also is it 64 bit, what core, My 2800 with stock cooling ran 32C with AS5 with 100% load. Make sure its properly seated without too much TIM. Odds are its the CPU fan thats the Issue the AMD stock coolers for 64 bit CPU's work great... As long as its at stock speeds. Check all your Bios settings double over make sure Volatage is in place for stock.

DO as RM said and take the side panel off, its tottally irrelevant if that fan config worked in the past as this is a new CPU you may need to change stuff around. If you can mount a new fan on the HS and see if that helps. because 69C is way to hot...

Btw here is the Conversian formulas F -> C ( F-32)/2=C C-> F (2C)+32=F
(170F-32)/2=69C

I agree with what you're saying, if you have another probe thats giving you similar readings then we know the cpu temp probe is probably right.

Thing is I wouldn't expect the temps to go straight to 70 from a cold boot, i would expect it to start at 20 and rise accordingly.

I know your saying your cooling was always fine before but is it only now that you've taken an interest in the cpu temps?

Also as5 is way better than the stock stuff and one tube should last you forever.
