couple of watercooling questions

[Tyson82]

Okay, just a couple of quick questions.

First, I followed the recommendation of trout on this forum and changed over from a fill and bleed to a t-line. Much better. I am however having a hard time getting all of the air out of the system. My radiator is the topmost component in the system and has some air in it. I can hear it when I turn the system on.

The system has been running sealed for about 2 days now. Ive tried turning the sytem on its side and partially upside down, but to no avail. Any thoughts would be great.

Also, my temps, which are probably related to a great extent on the above, are a little higher than I expected. Im running my mobile Barton at 1.725v on an older Silverprop cpu block. Im also running a DD maze 4 gpu block and a DD chipset block with a Swiftech 180 gph pump.

My temps are running around 35 to 40 degrees F over system temp. Does this sound a little too high?

Any thoughts are welcome.

And I might upload some pics later today.

thx

I'm not terribly familiar with watercooling (actually wandered into this forum by mistake ), but all you'd have to do to get the air out is raise a hose above the level of the radiator and start pouring in water until it's flushed the whole thing out. Keep the end of the hose submerged when you lower it to prevent introduction of air. Just like flushing a radiator or anything else - let gravity do the work for you and the pressure it induces will force out the unwanted air.

The 40F above system temp sounds normal. What is your system temp though? For future reference, celsius is generally the preferred unit when talking about system cooling (ie. it's more widely used). If your system temp is 35C and your final CPU temp is 40C that's perfectly fine.

The downside with t-lines is that they take a long time to fully bleed out the bubbles. My system has been running a few weeks straight, and while the bubble noises stopped after the first week, I can tell that trace amounts of air are still being bled out little by little because the water level in my t-line has been decreasing slowly. Give it time.

I am currently running 19c system and 39c cpu. Of course those arent accurate, but the spread is close enough. so is that about normal? I had thought that I would get closer to system than that.

And so far my overclocks arent what I had hoped either. That may come with time though.

Ok, the 19C system is nowhere close to being right. Normal system temps are around 30C and usually a bit higher. Considering that your system temp in actuality is probably around 30C, the 39C CPU temp is nothing to be worried of.

What do you mean by "come with time?"

 

[Tyson82]

the system temps are probaly right. We heat with a wood stove and its oon the other end of the house. hehe

And I mean that as the system burns in, like the artic silver burns in and the air gets worked out and I spend more time fine tuning the overclock, hopefully Ill be able to get higher. If not Ill be ticked that Im the only guy with a 35w mobile barton that cant hit 2.3ghz
