thanks but that doesn't help much
Looks like i have to answer myself LOL
Just received my custom made for pc (meanwell) psus from Kayl to overvolt pump to see if i can increase flow/pressure and performance - one does adjustable 10.85v to 13.59v other does upto 13.81v adjustable with pc relay switch
Top right pic you can see the white plastic dial to adjust the voltage output. I marked the max voltage output on the black switch/relay box myself to tell them apart
Before i had my MCP650 pump at 12.4 to 12.6v via my pc's psu which meant i had to overvolt my psu's 12v rail and all 12v powered fans and 12v rail using devices. But now i can run pc psu closer to 12v and still shove some volts up my pump
This is with MCP650 at 13.23v - seems to get a bit more stable and finally completed 32M at 3024mhz! Timings were looser than my sub 24min time at 3015mhz though heh.
These custom psus are awesome since I'm no electronics guru so saved my time and possibly blowing up my pc gear trying myself and got Kayl to do all the work
Kayl did an excellent job as last night i let the psu run my MCP650 @13.23v overnight and no probs. Noticed post-load temps drop to idle levels alot quicker now.
i.e. with 1.55v vcore with Swiftech G4 Storm + Thermochill 120.3 with 6x120x38mm Panaflo 103cfm fans
room ambient = 27.4C
before at 12.4-12.6v on MCP650
before stressing cpu idle = 38C
cpu load = 49-52C
post stressing cpu idle = would drop to 40-41C for 1-3 seconds and then drop to 39C then 38C
now at 13.23v on MCP650
before stressing cpu idle = 37-38C
cpu load = 46-51C
post stressing cpu idle = would drop immediately to 38C
I guess the custom psu would have better improvements overvolting MCP600 or MC350 pumps but seems MCP650 is liking it too
Going to play with the voltage output and see what's best for my MCP650.
edit:
I upped the psu to 13.49v for my MCP650 pump
2808mhz at 1.408v (112W)
ambient = 27.8C
cpu idle = 34C
cpu load = 45-46C
C/W = (46-27.8) / 112 = 0.1625
