my gpu is getting too hot

butaixyz · Oct 14, 2014

I have just installed a new amd r7 250
My pc is i3 2100
Mobo dh61ww
6 gb ram
Frontech cheap psu 450 watt (single rail 12 v 19 a)
Cabinet same frontech cabinet
Idle temp is 35 celcius
But while gaming it reaches upto 90 celcius and prcsr heats upto 70 celcius
Is it normal?? Or anything wrong in my pc? Need help

'Upto 90C' is fine, 'continously in 80-90C' is hot. 70C is fine for CPU. Stress test the CPU with Prime95, if shouldn't go over 80C normally. And GPUs can tolerate upto 100C spikes, but if its constantly in 90C range, it's not good. 70-80C is fine for GPUs.

But when i am gaming its contiously heated upto 90 celcius. But when i just stopped it comes back 35 in couple of minutes

Looks like R7 250 should be around 65c on full load.

Are you overclocking the GPU?

That PSU is could be a problem too...

butaixyz · Oct 14, 2014

No i am not overclocking it.what would be the probable solution??

cowboydude99 · Oct 14, 2014

Either bad GPU or PSU.

What GPU were you using before?

Is the fan working on the new GPU?

2 easy solutions.
1. Clean up or increase cool airflow from pc intake fans to gpu and exhaust fans. Good airflow through a case is very important for reducing temps.
2. Turn down any anti-aliasing etc. The r7 250 is a lower power unit, so won't handle too much intense graphics.

Again, upto 90C is FINE, modern chips can withstand 100C+ temps, though it's obviously not recommended. Downlaod and install MSI AB, and post a snap of GPU temps while peak gaming.

Moreover, if the card is old, you may replace the thermal paste, as the current one may have dried. Stress test the GPU using Fire strike, it would throttle if the temps are severly high.

My pc is 3 years old but i recently bought that gpu
And the gpu fan is working perfectly
Should i replace my psu??

MeteorsRaining · Oct 14, 2014

A third time, are the temps constantly around the 90C level or they occasionally rise to 90C?

cowboydude99 · Oct 14, 2014

Personal opinion based on the info:
Either it could be dirty gpu - but it is new, so I doubt it.
Bad GPU - possible
Not sufficient airflow in the case. How many case fans do you have? Are they all working?
The GPU fan isn't working - can you check on this?

The R7 250 is safe up to 90c, however reaching that isn't good. Most reviews I looked at show a load temp of 65c.

Bad power supply- your PSU could be supplying a bad load causing too much power on the connector, which would cause more heat.

Try swapping the GPU power cord with another one.

butaixyz · Oct 14, 2014

After half an hour of extensive gaming the temp is continiously around 85 and sometimes reaches 90

butaixyz · Oct 14, 2014

Prcsr also heated upto 70 celcius
Just gpu and prcsr fan
And the gpu fan working perfectly

MeteorsRaining · Oct 14, 2014

Looks like bad voltage ripples via the PSU, its not supposed to be over 80C constantly, replace it with a 400W+ PSU from Antec/ Corsair/ EVGA/ XFX/ SeaSonic if possible, they're much more stable.

cowboydude99 · Oct 14, 2014

What is the exact GPU model?
What CPU cooler are you using?
What CPU do you have?

butaixyz · Oct 14, 2014

Sapphire r7 250 1 gb ddr5 with boost
I3 2100 3.1 ghz

cowboydude99 · Oct 14, 2014

What CPU cooler? Stock cooler?

MeteorsRaining · Oct 14, 2014

CPU temps are fine.

butaixyz · Oct 14, 2014

Yes stock cooler

cowboydude99 · Oct 14, 2014

I could only find one review for the Sapphire r7 250 1 gb ddr5 with boost.

Load temps were 71c.

cowboydude99 · Oct 14, 2014

As I said in my first post... the PSU is probably the problem.

Replace that for testing.

butaixyz · Oct 14, 2014

So i have to change the psu or the cabinet!?

MeteorsRaining · Oct 14, 2014

PSU is the issue, bad voltage ripples resulting in high inrush of current. Change it.

cowboydude99 · Oct 14, 2014

Change out the PSU first to test.
