Rebuilt pc, high temps, bad loop?

post #1 of 7
Thread Starter 
Hi All,
Having a temp issue I'm hoping someone can point out and laugh at me for.
Pics:


Sorry, thumbnail for the 2nd pic wasn't working.

I loaded the original settings from my old build (same cpu/mobo):
(pump is in the bottom compartment).
And saw CPU load temps that were hitting 75*C and up - over 10*C higher than my old temps (~65*C full load). Obviously after seeing the temp go into the 70s, I turned off the power pretty quickly.

The things I changed between the old and new builds was the fluid, fans, res/pumphouse and the order of the components in the loop.
The res and pump were both used in another PC previous to this.

What could I have done to get such a big change in temps?

I reset the bios to defaults and got the following:
Full load max temps after 5 mins (AIDA64)
CPU-38*C
Cores 1 through 3 - 55*C
Core 4 - 53*C

Should the variance between core and cpu temps be that big?

PC consists of:
Core i7 940 - DD waterblock
EVGA Classified 3-way - EK waterblock
Laing D5 fixed speed pump
XSPC res/pump housing
Tygon 1/2" tube
Koolance red UV fluid (old build was Feser One)
Scythe Gentle Typhoon 1850rpm fans (old ones were Yate Loon 2k rpm)
DD Black Ice GTX 360mm rad
Coolermaster HAF-X case

I was running a BIOS vCore of ~1.55v Without Vdroop.
Haven't had much time until now to do more than the fast and nasty overclock method (turn stuff up till it works). I was hoping to fix/work on my OC with this build, but then this issue with temps has popped up.

Air bubble in radiator.

Is your pump working? (dumb question, but you never know sometimes...)

CPU block seated correctly? I had the same DD CPU block once, and it was a pain to seat correctly.

Those are the only 3 things I can think of at this point.

True. Fluid and Fans were listed in my parts list:
Koolance red UV fluid (old build was Feser One)
Scythe Gentle Typhoon 1850rpm fans (old ones were Yate Loon 2k rpm)

Loop changed from "res-pump-cpu-mobo-rad-res" to "res-pump-rad-cpu-mobo-res". The noob sticky suggests the latter to be a better option.

The pump was operating standalone with an EK multioption res 250 connected by tube

If those fans on the top rad are in push then no wonder you have higher temps. Look at all the heat you just shoved in the case with those gpus.

exactly what I was thinking! Also, every lane has something in it adding to the heat.

Also, the variance between the core temps and the cpu temp is normal. The cores will always be hotter.

Nah, they're in pull.
I chucked my Yates on the top of the rad to check it wasn't the Scythes failing. Don't fit great due to the case mounts, but temps didn't change noticeably so I discarded that idea.

Now that I've had a sleep and thinking a little more clearly, as rubix suggests, a badly mounted cpu block would explain the jump in temps. I'll have to re-seat it when I get home and go from there.
