i'm currently running a swiftech H20-220 APEX ULTRA kit. at full load on my quad i'm getting 50-52c on the hottest core. my quad take a bit more voltage than others to get stable at 3.6, but to get 3.8 or higher takes almost 1.6 volts and then the heat becomes my enemy at that point.

so i bought a new waterblock for the cpu and a new rad today. i got a thermochill 120.3 and a dtek fusion with a nozzle set. i assume the pump that came with my original kit will be good enough to use with that block and rad. it's a MCP655 which i believe is a relabeled laing D5. am i correct in that assumption?

also how much lower do you think my temps will drop?

Yea its the same pump.

At full load 50c at 1.6 on a quad is good IMO. I don't know if your really gong to see a big drop in temps.

Taking sand paper to your cpu could help, or removing the IHS(Good luck).

i dont imagine you would get too big of a performance increase. mabye 5-6c lower load, you would see a much better difference in load temps if you just added the radiator to the loop rather than replace the existing one. i have the same pump, waterblock *d-tek fuzion w/ quad nozzle* and gpu waterblocks w/ a 1.120 and 2x 2.120 rads... when i added the 2nd 2.120 rad, thats where i saw a drastic performance increase. simply swapping radiators was not satisfying what so ever :(
