High case temps with WC- leading to high liquid temps

post #1 of 15
Thread Starter 
I'm running a full W/C setup in a Lian Li v2000b- using their stock fan, my case temp idles at approx 50c- this is unacceptable. Problem is, I'm using all but one of my 5.25" racks, otherwise I'd mount a 120mm to get flow going. Anyone have ideas on that?

The big problem is that when startup occurs, I idle at 27c and load at 38c. After leaving it to idle overnight, it climbs to 38c as the case sits at 49c. I run a PA 160 radiator with a Panaflo fan hooked up directly to the powersupply- do I need to hook it up to my fan controller and feed it 20w to see if it'll run faster than it is?

I run a 2700mhz clock on an x2 4800+ at 1.42v and I want to hit at least 2800, but I should be running 38c under load, not at idle.

Any ideas, comments, etc are greatly appreciated- thanks!

hmmm.. thats definently not normal. are you cooling the video card aswell? is there alot of air in the lines? i think its odd that your ambient temps are that high?! how hot is the room that its in?

room's definitely not 72F, but it's not 90 or anything. Lines have been bled and bled and bled- the only thing I can think of is that the RAMsinks are heating up long-term and it's actually heating downward, as it were. But there's a maze4 GPU block on an x1900xtx- a card that idles at approx 48-53c on water, which would be about right to get abient temps to 50c... but it's heating up the reservoir is what I think is happening...

I may pick up one of those PCI expansion slot exhaust fans and see if that doesn't help.

Any other thoughts?

I would venture a guess that the x1900 is really heating up the water inside of hte lines. That card runs at 80+*C under load sometimes reaching 90*C. Leaving it on or playing games for a little bit will slowing bring the temperatures up and then you're left with something a little less than air. Even leaving it on idle will eventually heat up the system if you cannot extract the heat fast enough

The only thing I could think of is to run a separate radiator for the x1900 to cool the water down somewhat before it goes to the other radiator.

What kind of set up do you have becasue if you're running a single rad for that kind of system then I'm not suprised at the temps. If you're running a dual or triple then it seems kind of odd

Here's my WC setup-
Danger Den Maze4 Delrin top GPU block using Arctic Ceramique with Swiftech all-copper ramsinks on a x1900xtx running at 697/798 core/memclocks
Swiftech Appogee block running a x2 4800 oc'd t o 2.7 ghz stable at 1.42v
Swiftech MicroRes
Thermochill PA 160 (Supposed to be almost as good as the HE 120.2/3) using a shroud in pull configuration exhausting out the front with a Panaflo M1A fan running off the powersupply
Laing D5 pump on setting 5
All using Clearflex 1/2" ID tubing with band clamps
MCT-5 for coolant
Bled the lines for 6 hours, placing the reservoir at the highest point in the loop, then setting it on the upper case floor.

I will try leaving the case side off tonight to see if that helps any- if it truly is case temps that are causing the reservoir to heat up in such a fashion, this may solve the problem temporarily, but I am at a loss as to how to maintain a cooler case other than to forfeit a PCI slot or a 5.25" bay to a cooler. Other than that, I will be putting the 2x80mm in the back of the v2000b above the PSU in push configuration toward the radiator to see if perhaps I can convince a laminar flow to be beneficial to cooling the radiator above and beyond the Panaflo. If not, I may consider another shroud and configuring in a push/pull config and replacing the stock fan from Lian Li for the 120 rear exhaust with something with a higher CFM- another Panaflo, perhaps.

Anyone else have any input? Are my ideas sound or am I shooting in the dark, here?

I think your problem is your rad. You need about double what you currently have to cool what you're trying to cool

You're still not giving hte water enough time to give off the amount of heat that is in there. By having a 2-pass heatercore you will give the water more time to pass through, giving it more exposure to more surface area twice as long as a single radiator

I would almost say you should run a dual radiator just for the x1900XT and then pass it through a single for the CPU since tht GPU gives off so much heat

well... dual pass doesn't really mean the water stays in the rad for longer periods of time. dual pass and single pass the water stays in the rad about the same (single pass the water makes more revolutions around the entire loop so total time in the rad is about the same)

I really think your problem is your rad. it jus doesn't have enough surface area to let the heat out. Most people with similar setups are running dual or tripple rads or dual heater cores. I think an upgrade is in order.

have you tried leaving the side panel off for one night ? and see if the temps go as high you might not move the air in the case casuing that you only have hot air in the case and you dont get any new cold air in....

**OFF Topic**

hey Devman I'm thinking of buying the same case as you have how do you like it
