Custom loop, temperature issues! Please help if you can.

post #1 of 8
Thread Starter 
Hey guys

I've run into an issue I can't seem to fix.

So I've got a dual block watercooling setup with a raystorm on my 2500k and an original EK block on the gtx 680
Both the processor and the 680 are overclocked but the temps seem quite high on the cpu, with 40c idle and nearly 100c when IBT is abusing it.
The gpu shows 27c at idle and 44 under furmark,which seems roughly right given the amount of rads cooling the setup?

The system is set to go: res /pump /240 block /240 block /120 block /CPU block /GPU block /res

There are 2 240 rads and 1 120 as it's all I can fit in my case, and the 120 and one of the 240 rads are push pull so there should be no problem carrying the heat way?
The remaining rad is just on push for the time being.

I've tried reseating the cpu block several times and nothing seems to make a massive amount of difference..
I think i'd be right in assuming a figure around 80 tops would be ok for the cpu?

Any ideas?

are you sure the in and out are correct on the raystorm?
what are your clocks, ambient, voltages?
got pics to post?

Hi!

Thanks for getting back to me, the ambients today are 17c
The CPU clocks are 5ghz at 1.488v LLC level 1
The GPU clocks are 1259 boost/1802 memory at +100mv core

20130824_181817.jpg

It looks as if the raystorm is strung up right..
this probably doesn't help decipher what's going on in there?

that 2500k shouldnt be running that hot at all even with those volts. and older asrock boards reported lower than actual voltages. i dont know about that particular mobo. i still wouldnt push that much.
how are your temps at lower clocks?

That's what I thought! I had lower than 100c at the same overclock and voltage when using my nh-d14..it was a lot noisier and unstable though...
Ok so I've rebooted to stock and idle temps are exactly the same, which isn't much of a surprise, due to speedstep or whatever it's called now.
The highest temp. I've got at stock is a measly 46...something is very wrong here.

raystorm is right. hows the airflow? possible trapped air, not enough air flow. sure the fans are blowing the same direction(not pushing against each other)? have you tried to turn the pump up to 4?
air flow or trapped air is all i can come up with, unless you left the plastic on the raystorm.

*EDIT* - ive got the same rad space and an extra gpu in my loop with higher ambients(29*) and get max 63* on my 2500k. granted i only push 1.336v though. you still shouldnt break 70* from what ive seen and probably closer to 65*.

Airflow seems good, if I turn the fans right up it just seems to make more noise and not drop temps any more.

I can't really see it being anything else as the 680 would be getting very hot too.
I usually have the pump at 3 because it seems to be the best balance between noise and cooling ability.

The only reason it was at 5 for that pic was that I was trying different things to get temps down,
incidentally: cooling capability seemed to decrease at 4 1/2 - 5 on the pump setting.

I've been through everything,the only thing left I can think of is the raystorm has gunk on the internal micro fins as the
CPU isn't going to get massively hot at stock anyway..the fans are orientated as they should be so I guess i'll break
the lot down and see if the block is the problem here.

Thank you for your advice.thumb.gif
