Hi killme413


At first I didn't think it would be possible to overclock an Opteron system. I had read several sites say you could achieve a small increase, but nothing significant. I only planned on water cooling the CPU's because I thought it would look nice, and keep noise down.

Until about 6 weeks ago

The guys over at 2CPU who managed to get their hands on Tyan Thunder K8WE sample boards (its a dual opteron board based on the nForce4 chipset) found out that this board was something quite special. Tyan planned on supporting the nVidia nTune utility which would allow for overclocking, but more than that the sample boards have shown they are very capable, with the BIOS being quite feature rich.

Check the thread out here - 2CPU - P4N's Extreme S2895 Thread

There's a lot of talk about getting Opteron 244's (1.8ghz) upto 2.6+ Ghz

With this new developement I'm back on the horse for overclocking this system, but as you said, I've still gotta make it look just right!


I'm going to go all out when it comes to planning the cooling for this system On top of the watercooling system I outlined in this thread, I've decided to invest in a mCubed T Balancer controller system, which'll let me monitor water temp, flow rates and temperature of different components, and according program the software to control my rad fans

When it done it'll look something like this :



Except mine will also have a window

This would heat the system up



If I pushed air from inside the case through the radiator and out, my water temperature would rise. On the other hand if I pushed cold air from outside through the radiator first, my water temperature would go down, thus cooling my CPU etc more effectively.

hehe.. But with a few big fans the air inside the case will have no time to heat up anyways, it will always be fresh room-temp air inside the case thus it only takes like 1s to replace all the air inside the case..

And blowing hot air inside the case will cook all components including hoses and waterblock and will rise the temp on every single component in your system..Your pumping something like 300W of heat right into you case! it's like trying to cool a CPU when a blowdryer is trying to heat up the block at the same time

No response to why using a big tank? and pump?

Im not full of shit, i know fhysics and i have experice from several WC systems..

I think I'm going to have to experiment a bit, swap the fans around and check the results My previous watercooling rig used a radbox so this wasn't a problem I had to tackle.

Sorry I forgot to post this in my last reply; I'm not going to use a big tank now. Instead (hopefully) I'm going to use two of Trodas' Tank O Matic reservoirs This'll look a LOT better, and each loop will get its own res. They'll only hold 200ml's or so. Mounted under the res each one will have its own MCP350 (the newer ones with the flow monitors.)

Please don't think that I think your "full of shit", I really don't, and I apologies if you got that impression. I appreciate everyones replies

Forgot to add about the harddrives (I seem to be very forgetful today heh!)

I wish I could watercool them, but the way they are mounted in this case its very difficult to get a block in there. There's no way to mount blocks on the sides, only top or bottom (and even then the gap is only 10-15mm thick).

BTW your rig is amazing I especially like the harddrive cooling. What is the RGB PCI card ?

[killme413]

yeah those tano-o-matic are really cool and easy to get rid of bubbles and easy to fill =)
And MCP350 pumps are really cool, acctually they are used in Mac G5 ! =)

Wish you would conside harddrive cooling on the sides of the disks.. I love mine just too much. NO disturbing noise from the drives it's so good when i use the compuer as HTPC.

The PCI RGB card is an Realmagic X-card, (mpeg card), can do divx aswell =) Coped with TVedia software it's a real cool HTPC system. That RGB scart connector i made my-self, but the pins are there on the card =) dolby digital output aswell. Really love it!
