So what do I do about it please?

You need to lap it. Basically you are sanding the HSF on the chip until it is level.

Start with 400 grit sand paper, placed on glass or another flat surface. Lightly pushing the chip bottom to top, then at a 45 degree angle then 90 degrees etc. Personally I just rotate the chip instead of changing sanding motion. after the chip is flat with 400 move to 800. Then move again to 1500, to get as many deep scratches as possible out. Make sure to grip the edges and do not push down in the center.

Forgot to add there is a nice photo lapping guide. If you can't Find it let Us know and I will try to locate it when I get home.

Could it be the restrictive block causing this or something else? Is there anything else I can try like better fans you could recommend?
Do you have a desk top meter so you can watch CPU activity? That rise in temp's is probably just from back-ground activity...Speed Fan has a activity monitor in it..|MG| SpeedFan 4.34.

Some higher cfm 120x38mm fans should help...Does your rad feel warm to touch? If it doesn't the fans you have now may be enough...

Does it seem like your getting good flow through your loop? Did you clean out your blocks before you used them? They can have crap in them sometimes that will kind of plug them up and hurt your flow...

Hi ira-k, I would also have thought that about the back-ground activity but a jump in temps from 30c to 46c sometimes seems a little bit too much. This happens to jump that over a split second and then drops back to 30c something like 40c-36c-32c-30c if you know what I mean. The fan's most likely are not the problem then as their quiet cold to the touch all the time. I think the loop should be clean enough as its been emptied and refilled 3 times so far for alterations. I'm hoping to get time to lap the cpu and block tomorrow so if I do I'll post back. Thanks for your help with this.

Hey its NP..Let us know how the lapping does, if its still not wanting to do right we can try to figure out what else it might be...
