Overheating!!

[Helllearner]

I have the same problem. My computer in idle is 60-70*. No clue why.
I just changed my graphic card from a radeon hd 4350 to a nvidia 9800 gt.
and when i play a game it goes upto 90*!!

My comp specs.

Amd phenom ii x2 545 3ghz
Main board is msi 785gt-e63
DDR2 4gb ram
nvidia geforce 9800gt 1gb
my psu supplies 450


1) Nothing overclocked.
2) only started heating after i put my new graphic card.
3) i got 2 fans in my cabinet (4 overall with the cpu fan and the psu fan)
4) All the heatsinks etc are stock.
5) My cpu is kept in computer desk enclosed from the left and right side. front and back are open. My 2 fans are on the left hand side (cpu facing me). They both are exhaust fans. ( i had no heat problem with my old gpu )

Please i really need help.
My cpu supports the load? Im really new to this so im just gona clear my doubts too hope u guys dont mind
What is the problem?
What heat sink do i need to buy? Will it fit in my motherboard? How much will it cost ? We have to put some paste before applying the heatsink?
Is it my psu fault?
Do i need for fans?
Is my gpu spoilt?

Did you bump the CPU heatsink while installing the card? Sounds like it's not seated correctly.

Also when you put the stock heatsink on was there a plastic protector over pre applied thermal compound? You removed that right?

Either you bumped the cpu heatsink like Gunbuster said, or it sounds to me like your 9800GT is not getting ventilated properly. First check to make sure your heatsink is seated properly (all four pins are secure). If so, you could try running your PC outside of the desk to see if that helps. If that takes care of the temperature issue, than you'll want to figure out a way to run your PC outside of the desk all the time. Otherwise, post some pictures of your setup so we can actually see what you're working with.

Swap the other card back if its still getting hot then you probably need to reseat cpu with new paste.

If that corrects problem then it has something to do with your new card. does your system meet the specs for it? Is Gpu fan working?
BTW Your power supply is kinda borderline for that card.

i got win7 64bit

i cleaned the stock heatsink of the processer by water ( it was too dusty and i think i might have washed something sticky from it...dam...... )
do we get a seperate glue so that i can buy and apply?
A new heatsink would be beter?

i have placed it back properly tho.
i tried running it outside desk it didnt even budge 1 temp down.

But but but....... i replaced my new gpu with my old one and the temp amazingly decreased from 60-70 idle to 45-50 idle but while playing games it still reaches 60+

My new card has all it requirements

Does that mean my gpu is spoilt? or a new heat sink would help?

Thank you for ur support.

k i put the thermal compound and now the temp with my old card dropped from 45-50 to 35-40. but when i put my new gpu it just stays idle at 60 again.......... did i do something wrong??

 

[daniel49]

Will throw out a few ideas maybe one will help?

sounds like reseating your cpu heatsink helped you.
35-40 is pretty good.
why your cpu would get that hot because of your new graphics card is pretty weird. You can try adding some cooling, as someone suggest earlier maybe its not well vented enough.
what utility are you measuring the temps with? maybe there giving you errant numbers.
Have had that happen before with a motherboard that needed bios update. So Check for bios updates.
You could try downloading speedfan or everest and see if temps are any different?
any different settings in the bios to try for the gpu?

 

[Helllearner]

I think it is pretty well vented....
how can a new gpu just raise temp by 30-40 degrees???
im using core temp and speccy to measure my temp they both show the same temp.
my bios is latest version

My gpu core speed is 540 instead of default 600 by nvidia specifications. is this the problem?

i will try downloading speedfan and see if it gives diff results

Edit: i got installed speedfan and these are my temps
i got a amd phenom ii x2


temp1: 36
temp2: 127 ( 127? this thing wont even fluctuate )
temp3: 37
core: 36


fan 1: 12 rpm
fan 2: 2974 rpm
fan 3: 0

fan 1: 3417 rpm
fan 2: 0
fan 3: 0
This is what speedfan is showing me. I dont understand the fan readings so are my fans perfectly working?

 

[daniel49]

can you change the core speed and try it?

The fan running 12 rpm is pretty suspect

 

[Helllearner]

I dont know how to overclock a gpu or a processer not even basics.
So i wont take the risk or i might damage my hardware.

 

[daniel49]

inspect all your fans and find out which one is barely turning.

Try this for the temps

Try to clean all the dust in the video card.

I only had ATI lately but go in your video card application and see the speed of the video card's fan. Do you have the Nvidia System Tools installed? Or this:

[Helllearner]

I checked all my fans and they all seem to run pretty fast.

I have cleaned all dust from the gpu and the cpu etc.

I have xtreme tuner for the nvidia fan control speed. it is set to automatic. i set it to full and it made no difference.

 

[daniel49]

according to what I have read those cards can average 85=90 C.....evidently that heat isn't being dissipated fast enough and is causing your higher temps.
If it were me, I would add more cooling, and if that didn't help return the card.

 

[Helllearner]

A new heatsink would do?
tell me some good ones to buy plz

that will cool your card but the heat still needs to be vented by increasing the airflow through your case I would add additional fans first, but if you wish here are some coolers to look at. If you want a specific recommendation I'm sure you could get 20 suggestions over in the hardware forum. But really theres no substitute for reading the specs and reviews on your own
