How are my temps?

Very nice temps actually, its all good.
What was room temperature? Because that is very good for low end air cooling.

They're fine. As long as you're under 75 C or so on Prime 95 there's no reason for any concern

Below 60C means you almost have too much cooling going on (could set the fan to run a little slower, giving you a little higher temps but less noise).

Room temperature is average at around 21-22C. My case has two 230mm fans running at full speed right now, so that's probably why CPU temps are so low. I'm going to install a fan controller tomorrow and try running them at 50% speed instead.

why not just OC to like 4-4.5 GHz?

Average is a subjective term, you could live in London (which is currently in Winter) for all I know. Guessing ~30c?
The fan controller is a good move, don't connect the CPU fan to it though.

EDIT: So cold.
Damn, kinda disappointed in my cooling now. $200 watercooling kit and a 10c difference under load at roughly the same ambient temps. Though admittedly my chip is overclocked.

I edited my post with my actual room temps while you were typing that up.  



I'm running two Radeon 6870's and my PSU is only 750W (Corsair AX). I don't really need OCing right now and don't want to push the PSU to its limits.

Just so you know, you will top out the chip before running out of power with that power supply
