I'm not entirely sure how to word this in order to not get flamed by jaydee

My block I constructed, as in my previous thread, is completed and running on my testing system. After some tests, with a chaintech 7NJL1 (?) and a T-bred A 2000XP, I think I've hit a design flaw in my block. Basically, a huge temperature rise from 0.1 increase in voltage. This is all LM90 based, on the motherboard, and not the best testing method i realise (i am picking up a multimeter with a K type thermocouple shortly, which should be a bit closer to realistic), but I was wondering what a quick analysis from you guys would come to.

At 1.92ghz, 1.85vcore, i was seeing a 37 degrees under load.
At 1.92ghz, 1.95vcore, i was seeing a 42 degree under load temp. This shot up pretty damn quickly too.
Load was achieved using 2 instances of prime95 TT.

Im thinking its base thickness, as its only about 3 mm. The block is pretty low restriction, with my full set up connected (rad, res, block, pump) I'm seeing 1.5gpm, roughly. I think I'm right in thinking that the thickness is reducing the efficiency of the block, but was wanting a more experienced opinion.
