CPU temperature high!

I downloaded speedfan for my computer last night, it readed that my CPU temp was almost 80deg, I know this is pretty high, seeing as my comp had been pretty much idleing most of the day! I turned off for a few mins, then went into the systems bios, it still read 70deg there. The case ambient temp is in the low 20's. I then opened up the case, and wafted my hand over the components to see if I could feel and heat comming off them, when touched the CPU heatsink was as cold as it is when the comps turned off. I dont get how I can get a reading of 80deg. I have a zelman heatsink on my cpu, and normally have it running slowly and crank it up whilst playing games.
Any ideas where this heat is comming from?:confused:
 
First of all, I'd seriously get a new handle. You're really askin' for problems from members who are just looking to hammer on someone.

Second, make sure your heatsink is on properly, with the right type and amount of thermal goop. If it isn't sitting right, or the paste is wrong, you'll overheat. Your heatsink could be cold because it's not pulling any heat off the CPU!

Third, there's a chance your CPU sensor is inaccurate, because you haven't had time to put the CPU under any appreciable load. I ran into this myself, after reading that the temp sensors for VIA chipsets are not exactly very accurate. If you find this to be the case for you, you can get into SpeedFan's config settings and adjust the CPU temp reading to compensate for inaccurate sensors. :)

heres a screenshot. Only see two fans plugged in, because all others including CPU fun are running off a thermaltake fan controller.
 
YOU APPLIED SOMETHING WRONG PLEASE SWITCH THE HEATSINK...
no joke, those are DANGEROUS temps for a 90nm chip...
i thought 60C was high for my chip, and its dual core. single core should never even have to hit 50C
SEVENTY EIGHT THOUGH?!?!
WOW
wait, is that 130nm? either way its HIGH TEMPS! but 130nm its probably a little less dangerous... but you did something wrong... it shouldn't be that hot.
my old 3400+ 130nm never got that hot, never even hit 45C i dont think..
i wouldn't say its wrong if yur bios reported cooler temps, but thats seriously extremely hot.

No, the reading is wrong. The max temp for an Athlon 64 3700 is 70*C. If it was that hot, it would have shut itself down a long time ago.
 
doubt it.
i used to have a 3400+ man, and the first time i put the heatsink on i had to immediately replace it, readings were around 80C
im assuming its 130nm now lol
 
I did a couple of expirments. Let the computer idle for a while, turned it off, took the heatsink off make sure all was fitted ok there, it was. CPU was cool enough to touch.
Played call of duty 2 single player and multiplayer for about two hours, turned it off, and took the heatsink off, the heatsink was noticibaly warmer, bt still the CPU was touchable.

There is no way its actually running at 78*C! That screen shot was taken the first time round when I had left it to idle. It never went above 10% CPU usage, so theres no way it could generate the kinda heat it was saying!

P.S. In my first post, were I said that my heatsink was "cold" this was a bit of an exageration, but even so, it was still pretty damn cool for what it should be if the CPU really was running at 70*C!
 
Yea, according to verious sources, the AMD in my comp has a max temp of 70*C. Under loads should be around the 50*C mark.

The 3400+ can go up to 85*C.

The 3700 Clawhammer can also go up to 85*, but the Venice, Newcastly, and San Diego are all max of 70*
 
so you turned the comp off, took the heatsink off and then touched the cpu? lol yea, it'll be touchable by the time you do all that.
if the bios is giving such high readings, i'd trust it enough to reapply some thermal compound. clean it off with rubbing alcohol, and making sure not to put too much on apply some thermal compound. you only need about a bee bee size worth of the stuff..
don't touch the surface, and don't take the heatsink off after you put it on. that introduces new air to the surface and contaminates it.
after you've done so carefully, tell us what the readings are. if they're still that high, THEN i might say they're wrong...
its an abit board though, abit boards are normally up there with asus and such.

To get the heatsink off is pretty fast, the side of the case was already off, the heatsink is held on by two small clips, so once the comp is off, its no more then 5 seconds before I can get to the cpu. It was cleaned and new goop was put on each time, I actually checked the cpu with a temperature probe, ones you get for cooking (to see if your meats cooked or not), even so, the cpu was 20*C the first time, 27*C the second after a bit more a load was put on it, I cant see how in a matter of seconds the cpu can shed over 50*C of heat. I think somthing is just dodgy on the Mobos side not the cpu.
Bios readings are the same as speedfans, heatsink is the same as a mates, he has the same cpu, and has never had any problems. Its a zelman heatsink, so not exactly a shabby one, so I cant really find the fault to be with this. Im gona go out an buy a temperature probe thingy! Have that perminently attached to me cpu, so I can monitor it whilst im using it, see what that reads.

speedfan probably wrong

Yes, check the temp in the bios setting, mine had 3 shutdown temps avail, 60, 65 and 70 cel. Default with a new mb was off. I installed a monitor and it came up with 80c and wanted to shut me down, I immediately checked my bios and that was at 47c. So that cpu monitor was removed. I now have an ECS mother board, can anyone suggest a desk top temp monitor that will work?
