Should I bother?

I currently have a 120 mm. Black Ice extreme attempting to cool my pressy.

At full load my temp is around 55 according to speedfan which I understand
may be overstated by a few degrees.

I seem to have hit the wall at 238 fsb. Would a second rad added into the loop make any difference at all to my OC or would it be a waste of money?

Thanx for any advice!

P.S. All of my case fans are blowing inwards with the rad air being exhausted through a nasty looking hole in the side so the temps inside the case are good.

2 radiators couldnt hurt other than decrease your flow rate. I guess it would mostly depend on the pump you have.

That makes sense to me anyways...
