So my current pc is on its last legs its a HP Compaq dx2450 (don't laugh).

I am hoping to get perhaps another year out of it for some gaming. To do this my friend has kindly given me a Radeon 6850 to replace my current GT 420, which is by no means a gaming GPU. I have also purchased a corsair 600w PSU which I am going to use in my future build.

My question is do I need to add a case fan to my desktop to keep it cool. My current gt 420 runs at 85-90 degrees during a render test, which is way to hot, although it is quite old so the fan my not be working fully.

The case being a micro tower does not have mounting holes to add a extra fan, but I have no problem with drilling holes ect by following this video. https://www.youtube.com/watch?v=7wGlWZ24QsE

Thanks

Yes, definitely.
Unless it is ventilated like this, it is not a real computer:

It looks like you have a single 92mm exhaust fan in your chassis currently.
Although this does not give too much airflow, it is still better than nothing.
Your new HD 6850 is a 127W TDP rear exhausting card, so it should not add excessive amounts of heat into your case.

Probably you will be fine without additional fans, but a few more would definitely be nice.
When you have the case open to install the new PSU and GPU, check the front to see if there are any mounts for additional fans.
Probably you will have at least one free mount; probably either an 80mm or 92mm.

This is the front of my pc, doesn't look to hopeful for a mount space.

Hypothetically if I did put a side panel fan on to help air flow would I want it sucking air in or out?
