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.

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

Are you overclocking the GPU?

That PSU is could be a problem too...

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

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

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.

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

Just gpu and prcsr fan
And the gpu fan working perfectly

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.

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

Load temps were 71c.

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

Replace that for testing.

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

EVGA 430W is ultra cheap for $25, Antec VP450P is another good choice.

what is the rpm's your gpu fans are running at? On my gtx560ti classified without precisionX up the damn thing runs hot as hell but once i open precisionX it ramps the fan speed up and cools the card back down. I would never run a gpu without some sort of software like afterburner, precisionX or the asus version of those two........You can set custom fan profiles and it also controls fan speed to make sure the card runs optimal.

I personally wouldn't go for something at 430w. This means you could end up upgrading the PSU again if you plan to make any other upgrades later on.

Go for something around the 600w range.

Will corsair vs450 or cx430 fit in my cabinet?

Yes it'd fit, but please AVOID them, they're low quality PSU, EVGA 430W or Antec VP450P is much better in quality.

VS and CX are basically builder grade psus. They are just enough to pass the basic tests, the very basic tests at that, and thats about it. They'll work, just not very long, and not very well and they know that, which is why they have such short warrantys. They are the quality of psu that starts to die the day before you buy it and kicks the bucket the day after the warranty expires

Removing one side of the cabinet can solve this heating issue?? Also i notice that after closing the games the temp comes back to normal within a couple of minutes

Try with the case opened up. And it's normal for temps to reduce after gaming as the load on GPU and CPU gets less.

That's a normal temp for an r7 250. They only cool it with a small piece of aluminum.
