GPU thermal throttle

[SkixAces]

So today I bought a 2nd hand graphics card for 15 euro's to put in a dell pc I got for free.

The gpu I bought is the: Radeon HD 6450 1GB passively cooled

It's running fine, and as espected but I have found 1 problem.

When it reaches 70 degrees it downclocks to keep the temperature low. 

There is nothing wrong with that, but it obviously decreases my performance.

Now I wanted to install a fan on to it instead of the passive heatsink.

Does anyone have any suggestions? 

 

I don't even think I can install a fan on the card btw because there is no adapter, but there might be an option? Would it be oke to put a fan next to it, blowing on it?

There's PCI slot fans you can get pretty cheap.

Yes of course that would be okay.
You can also try to re-apply the thermal paste to get better temperatures.

Hmm, would it work if the fan is on the other side of the gpu? This is a dell pc with a very weird config on the motherboard

The fan has to be blowing towards the heatsink. If you can mount a fan to it, your temps will decrease dramatically, ive done that to a passively cooled HD 5450, and boy those temps surely went down.

you would want the fan blowing the heatsink of the gpu

 

u can try re-applying the thermal paste if you're daring enough

 

if all that fails, try getting a 120mm or 90mm fan to blow directly at it, duct tape the fan down if u must

[SkixAces]

This is how my case looks. The HDD is floating above the motherboard, en I am sure I can place a small fan under it.

Might even duck tape it like you said  Any small fans you guys can reccomend or is anything viable?

So I thought about it today and would it work if I cut a hole above the gpu in the case, and put a fan on it?

The air would be blowing from above it which is fine right?

Allright, nice. I really don't give anything about aesthetics. It was a free PC I got, and it looks pretty ugly, but that doesnt matter

Any recomendations? for a cheap, and (silent) fan that moves enough air to cool it?

Size doesnt matter, I dont know a lot about fans so don't really know what's good and what not

how tall is the side of the case? no point recomending a 120mm fan if it only fits a 90mm

Its actually the top :P. It's a dell pc that lays down. Here are 2 pics of the top view of the PC

So the size doesn't really matter that much. Smaller would be better though

imo get a cheap 90mm fan with pwm and control it with motherboard (if thats possible)

 

heres some fans u can consider

noctua makes great fans at all sizes
