My block and coldplate are both 1/4" thick, 50x80mm. I figured that this is still better than not clamping tightly, so i clamped it together and mounted it. Im not getting the temps I want though.

13c idle, 23 load (ish)
25c water
226 @ 11 volts (its a crappy old computer psu with only my blower on the 5v to load it)
2500M @ 2610, 1.9v

anyone else haveing problems with flexing?
Your block design is flawed for TEC use. You need two more bolts on each side top and bottom. Get the bolts as close to the TEC as possible to help eliminate the bending. A 1/2" cold plate will help aswell.
