Almost sure my temps are high because of air in rad. How can i be sure and to bleed RP-452X2 - Page 4

when you install it you screw in into the backplate then tighten those thumb screws until you cant tighten them anymore

I have almost the same setup as you, but with my GTX 580 in the loop, and my idle temps are about 28-32C, 45-55C Load for both the CPU and GPU with ambient 21-27C. Your overclocked 920 is fine with it's low voltage setting and not causing the excess heat. See specs and pictures (The Black Phantom Gallery) in my signature. I have my radiator turned the other way so there is no sharp angle going from rad to res, but others here have it your way and seem to have no problem, so it may or may not make a difference in your situation.

I also have a 5.25 reservoir, but with a less powerful pump (XSPC 750), so the reservoir may not be "sucky" as you think. It is merely a water tank, you fill it, pump pulls water in, tube brings water back. Nor is it a fan problem as the RX series works with very low rpm fans - even less than 800rpm.

As others mentioned, it may be either a radiator internal problem, contact of CPU heatsink, or pump problem.

Have you tried this: Edit: Sethmo posted same advice about flow, deleted my suggestion - sorry

Just curious:

Pump making any type of rattling or other noises?

Also, what fluid are you using?

Those temps are Celsius, not Fahrenheit, correct?

What is your room's ambient temp. Celsius?


Good luck, SS

Have you tried this:
- Put a longer tube going from radiator towards the reservoir, but leave the tube unconnected and going into a bucket.
- With pump is running, let the water come out of the radiator and into the bucket, and have a bottle of water to pour into the reservoir fill cap to keep the reservoir level high enough so the pump stays full.
This will give you an idea of the flow through the system. If the water comes out in a smooth, fast pace then your pressure is good. If it comes out in slow spurts or stuttering then you know there's either air in your system, clogging somewhere, or a faulty pump. Hopefully some testing will show the cause.

Pump is making very little noise and vibrating normally, did get noise at first but then no more. Using Distilled water with Killcoil.

I will try those 2 tips as other guys suggested it. I dismantled the entire system and plan on doing it out of the case to test it.

""As others mentioned, it may be either a radiator internal problem, contact of CPU heatsink, or pump problem."" This part really show you know what you are saying, some times people see not AP-15 fans and say ohh that's why temps are a gazzilion degrees higher

Also nice setup, are those 3/8 tubes? And i see a quick disconnect hanging there? dran line?

Lol yeah oC, and ambient is 28ish i guess

Lol scrathed the hell of my rad in the process.

Thanks, nothing special as far as looks, more of a work horse for me. Yes, 3/8 ID 5/8 OD sized tubing. I prefer this size as it is very easy to work with, does not kink easy, and does not take up too much space. Keeps flow rate even very well.

Yes, for the drain line I have a Koolance Quick Disconnect FEMALE, and when I need to drain I simply attach the MALE connector (which is connected to a extra tube) and it drains to a bucket. When finished I simply disconnect the Male and the Female seals close, then just fill up at the reservoir top cap.

I was curious about the temperature as you are farther South than most people on OCN. You are about 2-3C warmer then me in California. cheers.gif

Good luck.

This is the final setup 700

Temps were bad because of bad bleed of koolance bay res + block had base rotated my 90o

So ... after four pages of reading it is now fixed but you didn't post the new temps. That sucks. It's like your TV dying with ten minutes left in the movie.

I've made a new thread. But temps are ten celsius lower on idle and over twenty at load 44/59. Idle/load.
