The half power test actually went pretty good (The cooler is currently still running that way as it's so much cooler in my office). Sorry I didn't update yesterday.
My absolute low end is only about 12c°, but I ran a 15 minute stress test at 100% when I very first fired up the computer, so the...
I've used the meter against heat guns and it's always seemed pretty close, but that's at 1200w and 1800w tests, I've never tested the low end of the meter.
I'm trying someone elses suggestion today. Basically running 5 TEC's at half power. Don't have any high hopes though, I'm not sure that a...
Yeah, I threw the kill-a-watt just on the tower but I don't see the monitors making much of a difference, they should be running about the same all the time, so you can probably discount them.
Something has to be reading wrong on my meter. There is no way that this CPU is only drawing 60 watts...
Alright.
Some more testing accomplished.
With 2 cores disabled and HT off, the frequency at 4.4Ghz, the chip never really got over 30c°. Here is where the inefficiencies of my system are felt...
I ran the 100% load test for 20 minutes (Real Bench H.264 Video Encoding) and watched the temp...
Well crap.
So apparently my thermistor is a bit off in my Res.
So I un-clocked the CPU. Reached 10C in about 20 minutes, third TEC turned off, but I was seeing a discrepancy. My CPU was reporting 9C. Huh? Hmm, must be software not being accurate.
So I've let it run for about 20 more...
Sounds like your pump isn't working. Or possibly, there is a hose that protrudes from the case and is being pinched somewhere? A flow restriction could do that.
Is there a clear reservoir that you can see the fluid in? When you start the computer do you see water moving in the reservoir?
The more I think about it, the more all the differences are meaningless until I remove the OC from my CPU. There is no comparing the cooling capabilities based on the data we have currently.
By voltage and cooling wattage available, I am right there with you. The wider TEC won't make a...
Heh, I'm no math expert! I just like to play sometimes, real math experts baffle me, I have no idea how people can grasp some of those abstract concepts!
But using math, apples to apples, you are running 178.5 (based on the specs here...
I followed your lead on the reservoir. I think the loop total holds about 0.65 gallons, the res is just about 0.5 gal. I got three full flushes out of 2 gallons and still have 1/4 gallon left.
There is no 'data sheet' that I can pull up for these peltiers, they were a custom unit made by...
Oh, I'm not doubting that it works. Mine is able to cool to about 14C with the chip OC'd to 4.4Ghz @ 1.25vcore with the Cache OC'd as well, that's a TDP of close to 225-250 watts under full load.
If I were to turn my OC off and run this at stock speeds I bet I could get down to the 10C mark...
Got my fans this evening. Got them installed, not a huge change in res temp. The heatsink temps did drop quite a bit you were 100% right there! They are no longer hot enough to cook on! I'd be that they are probably around 35-38C°.
The res temp has stabilized about 14C°. I just don't...
