First LC loop, temps okay alright?

post #1 of 10
Thread Starter 
Hello OCN,

got my first waterloop done, now im asking you guys if the temps are okay.

XPSC RX360 with 3 800rpm fans, heatkiller cpu 3.0, heatkiller gpu³, artic silver 5 compound.


i7-920@4.2GHz w/HT - 1.36v

75-77° prime in-place-large


GTX470@800MHz - 1.025v

50° Furmark xtreme burning mode,32MSAA,1280x1024,post FX


whats your opinion? cpu seems a bit high for me.

CPU is a bit high it will go a bit lower as AS5 needs time to perform better.

Still I would suggest redoing the CPU part.

It looks a little hot but about right. With my RX360 and Rasa block with the fans at 800rpm I get 73-76 at 4GHz and 1.38V. Is there any way you could speed up the fans to check your temps at 1300-1500rpm?

that looks just a bit little high. make sure you got all the air bubbles out of the rad (this was my problem for a few days) and maybe redo your TIM with less and less. Its surprising how little of that you actually need. about 1/3-1/2 the size of a grain of rice.

you may also want to take apart the cpu block and remove any black stuff that may not have got flushed out before you set it up. I rinsed it a bunch, but after a few days i took apart the block and there was a bunch of black specs in the pins. I may check again today if i get bored...

also maybe just wait a couple days.. the TIM will set and the bubbles will work out. it should drop a bit in 2-3 days.

Thanks guys, ill just wait a couple days.

rep to all.
post #6 of 10
it might seem a bit high, but what order is the flow going ? because if its going from GPU > CPU then you could expect it to be higher...

i foudn the best way to get rid of bubles was to tilt the machine so it it on one corner.... that way the air will flow... with a bit of shaking...

I dont think that's really true. A liquid system will reach equilibrium as a whole over time. The order of your loop shouldn't matter, the water temps after the rad will be the same as the temps after the gpu after enough time has passed for stable equlibrium. Anyone have thoughts about that?

yes tilt/shake and squeezing the tubes, especially the one out of the rad got rid of all my bubbles.

Couldn't have said it better myself. The water will only be about 0.5-.7C warmer coming out of the GPU block than going in.

The OP's temperatures actually seem quite reasonable considering he has a 470 and an i7 on a single 360 radiator with 800 RPM fans.

If he upgraded to 1850 RPM GentleTyphoons he could always undervolt them when the computer is idle and his rig would be just as quiet as it is now, while having 7-8C lower load temperatures.

Yea...those temps seem just a tad high. I would take a look at your CPU block...maybe remove and clean it (inside and out) and reapply the arctic silver.

Question...when you built the system did you flush the radiator before you used it?

I have a 920 at 3.7GHz and it idles in my system at 34C and maxes out at 60C w/100% load. I'm running a EK Supreme HF kit w/single GTX460 in the loop w/3 Loons running 1100rpm pushing air out over the 360rad.

I haven't been water cooling very long, but I learned from posters on this forum that the order of your loop won't matter THAT much. Since it stabilizes eventually throughout the whole system. I did remember a few things this forum taught me
