I'm using Scythe Ninja for Cooler. At 1.4V, core temp never gets over 60C. Actually my Scythe is a Topower built. My 12V rails never gets below 12V during load and Conroe doesnt take up much power so I think my PSU is ok. I've power usage tester and during load my rig takes up around 200W so I guess my PSU should be good enough for it. Well I'm not really lucky in getting good CPU but I have to agree to that my PSU is not very good.
