Sporg Watercooling Work Log (56k warning)
Posted: Sat Aug 30, 2008 10:52 pm
First of all, a big thanks to everyone who chipped in with advice (especially martini161 and Bio-Hazard).
I have been experiencing high temps lately. I have never been happy with the CPU temps since I put this rig together and adding the HIS Radeon 4850 HD (Thanks LR!) has had an adverse effect on my temps. I am not sure where my screenshots are from before the upgrade to after and I’m certainly not going back now.
From Memory (all temps Celsius):
CPU (no load) = 58ish
CPU (load) = 65ish
GPU (no load) = 60ish
GPU (load) = 66ish
I had to use the ATI profile hack to get the temps to that level on the GPU. Prior to the hack I was in the mid 80’s. With the hack I set my fan default to “65” which I assume means 65% fan speed when my profile was active. I never tried a higher number to see how low temps would go.
Some of you know what I decided to do, but for those who did not know… In the spirit of experimentation I decided to take the plunge and drown my computer.

System Specs:
Case: Thermaltake Armor
CPU: Intel Core2Duo X6800
MB: Intel 975XBX2
GPU: HSI 4850 HD
Audio: Sound Blaster Audigy 2
PSU: Antec TruPower 650 Trio
RAM: 4GB Corsair XMS2 (5-5-5-18 800MHz)
OS: Win XP Pro (32 bit)

I spent several weeks reading and researching what others were doing and using. I didn’t really have a good solution prior to calling up my buddy Aaron (redneck fabrication specialist! plus he has a lot of tools) and enlisting his aid. After hitting up the LR forums and asking a lot of questions I finally had a parts list and was ready to order.
The meat of the list:
CPU Block: Swiftech GTZ (new to the market and is compatible with the new Intel chips)
GPU Block: Swiftech MCW60
Pump: Swiftech MP665
Tubing: Tygon Silver ½” ID x ¾” OD – only ordered 4’ and was not enough to complete the job
Heat sinks: Bought a Swiftech heat sink kit for a different graphics card (NVIDIA 8800 series), but it contained everything I needed.
Heater Core: Swiftech MC320
Fans: Yate Loon 120mm – 12v (total of 3)
I found the best overall prices at two online e-tailors. I ordered everything on a Friday and by Tuesday I had both packages.

Day 1
I took Friday off and went over to Aaron's with the items that would make this project a challenge (think radiator). The greatest challenge was where to mount the radiator. I originally had thought that maybe I could somehow mount it on the side, but half-recessed into the case. Once we got the case apart it didn’t seem like a fun idea. Another idea was to mount on the top. Andy (another buddy) suggested mounting it perpendicular along the top. The more I thought about it the less I liked that version. So I decided that I wanted to mount the radiator parallel with the top of the case and have the hoses come in (and out) over the drive bays.
Top of case with holes drilled.

Aaron and I spent at least an hour walking around Westlake’s Hardware looking for ideas on how we could mount it on top. We decided on something, but I changed my mind and returned everything later in the day. Fortunately the holes Aaron drilled would work perfectly with what I had in mind. Earlier Aaron had suggested using springs and mounting the screws through the centers. I really liked that idea and went with it. What I got was about a 10" long compression spring and just cut sections off to length (1 5/8" I think).
Radiator mounted on springs.

Must be careful not to screw in too far! Don’t forget to look at that sexy, shiny fitting!!!

We also cut a square out of the back so that I could make sure the back plate for the CPU block would not fall or move when installing. I copied this idea from Dan's log.

So with the radiator mounted it’s time to work inward. I installed the motherboard and loosely mounted the CPU block. Then I installed the pump. I love this case because there is just so much you can do with it. I had to route out two holes to fit the screws for the pump.
Next up the vid card… I had to take off the stock cooling solution.
As with many things in life it’s important to remember that often-times things come apart easily when everything is removed. I barely pried on it before noticing the back side!

For anyone who is curios and wants to see what’s underneath the stock cooler I have a fuzzy picture for you.

The pads that came with the little copper heat sinks are absolutely worthless. Luckily the kit I ordered came with an Arctic Silver Compound that is rather permanent. There are numerous notifications on their website about how you should never EVER EVER use it on a processor.
Water block on with heat sinks. I bent the prongs on the heat sinks directly below the water ports so that I could later install the hose and clamps. I later found that you could just snip the ends off, if you actually had a pair of nippers in your possession.

After midnight I got the hose hooked up, until I ran out…

I was irritated and stepped out for a smoke. This little guy is probably doing his part to try and get rid of some of the bugs.

Day 2
Visited Westlake’s hardware again and found some hose that ended up working. So, anyone who is familiar with this particular CPU block may see a mistake I made.

Okay, if you didn’t notice in the previous pic, then you should notice here. I sure was proud of myself for the next 30 minutes of flushing (until I realized what I did). At this point I was flushing everything out with a 50/50 mix of White Vinegar and warm distilled water.

There we go! That should be a bit better… The water block has a specific inlet and outlet side. I had the hoses backwards. Easy fix and was my biggest mistake (next to not ordering another 2’ of tubing).

After several hours of leak testing it’s time to throw everything else back in. This actually took much longer than it should have. I had a bazillion tiny bubbles that took forever to get rid of. On the flushes it did not take long at all to get all of the air out. I'm assuming that I didn't mix something quite right, so probably a little bit extra corrosion inhibitor.

Front of the tower. I repositioned a few things because the hoses run right through the top area.

A couple pics of the finished product.


With no load at all CPU is at 29-30 degrees and GPU is at 34.5 degrees (again Celsius). Firing up the fold@home GPU2 client and with a 95% load I’m getting 37 degrees. Fired up two iterations of SuperPI and set the affinity so that I have one running on each core. Temps went up a bit, but nothing like before. The highest I saw here was 39 degrees.
Please note that the fans on top of the heater core were not running at max speed. I have them set at about 50%.
This project took a bit longer than expected. Mainly due to initially not knowing how I wanted to mount it (the radiator). I also spent a few hours getting rid of air bubbles.
This was a fun project and I wish I had done it long ago.
