Will I See A Notable Difference? DD DB-1 vs MCP655

post #1 of 6
Thread Starter 
I currently have the following.

DD DB-1 Pump > Black Ice II Rad > XSPC Rasa Block > Swiftech Micro Res. All on 3/4" OD 5/8" ID hose..

The DB-1 pump is a 500 LPH pump, the 655 is a 1200 LPH pump, so theres no doubt its a faster, better pump.

But would it help temps? My 950 runs kinda hot, and I cant get to 4.2 now, I think I can get stable, but temps get to high on prolonged stress testing..

Was thinking a new rad too, but not sure if I can do both now so wanting whats going to help most first..

Thanks

if all your cooling is the cpu I cant say youll see better temps
if the pump is not pushing like it should then yes you will

the 655 is a nice pump I have 2 of them

what are your peak temps now and what size rad do you have

The rad is a 240, Black Ice GT (not GTX or Xtreme)
My CPU is hitting 70c now at 4.0 (1.352v) and whn I try to push for 4.2 @ 1.38v it starts getting up around 75 - 79c


Ambient temps are 75f and the airflow is good, have 2 yate loon high flows on the rad..

you would be better off with a thicker rad then pump (for now) that rad is thin like my 360 rad here , i got a 240 feser rad and measured the fin area The feser 240 was 90 and 360 was 100, So the 480 rad is 2 times larger in area of fins (to cool) of the 360 rad i got. 480 rad is feser as well.

thats not the problem I dont think

take the cpu block apart and clean it
flush your rad with vinegar and water then with distilled 2 or 3 times reassemble with some good TIM at least as-5
see what that does for you

what cpu block are you using

brand new XSPC Rasa block, just put it on last week, flushed & cleaned loop when I did it..

CPU runs hot, I couldnt break 3.8GHz on my TRUE while I was waiting on the Rasa to come in... Had the same loop on my Q9550 & i5-760 with a HeatKiller, and it handled them both.
