Need assistance. About to dump MCW50-T

GS400MAN · 07-27-2003, 08:20 PM

Hello All,

I picked up a Swiftech MCW50-T and some Tweakmonster Ramsinks for my water cooling setup. See below. THen the problems started.

First and most severe is that my system would no longer run stable yet alone boot at my 2564 mhz that I was proud to obtain using my Tc-4 block and other goodies.

So I figured it was the power supply. I currently have a TT 480 Pure Power with 18amp on the 12+ rail. Swiftech recommends at least 20.

So I wired in another power supple-TT 420- unit just to run my Swiftech GPU peltier unit.

With this setup, I still was not able to get past 2508 mhz reliably for the cpu (Prime certified before at 2564).

Temps:
My previous cpu temperature (off the mb) read 41 degrees idle and 44 degrees under a load. Now with the Swiftech, I'm at 51 degrees idle and 53 under load!!!!!!!

About 10 degrees hotter with this setup!!!

Setup:
1300 water pump. 1/2 Clearflex lines. Proradiator /shroud/enermax 120mm 94cfm fan.
13 case fans
D-tek TC-4 Rev 2.0 block

Yes, I can clock my 9800 pro straight to 520 mhz/ 400 mhz ram. However with the reduced cpu clock ,my system now scores lower in benchmarks.

So, what to do?
Do I:
A) Dump the Swiftech and get a non-peltier GPU WB such as a Danger Den or Gemini cooler. Will a non-peltier GPU block increase the water temp as drastic as this unit?
or
B) Get a peltier for the cpu? Extra PSU required.

Any advice would be appreciated.
thank you

Check your water temps, before and after. The pelt probably added a lot of heat to the water.

You can either dump the pelt, or run in on a seperate loop. On the other hand, it might be PSU related.

Thank you.

I decided to go the non-peltier route for the time being. Any suggestions on the best VGA water block?

Swiftech MCW50 (without the T)

DD

D-Tek

thank you again

That's fine.

The GPU waterblock design doesn't need to be fancy, any of them will work well.

Unless of course you're running an NVidia FX5900 Ultra, then you have to do this:

I'd just stick another heater core in the line to cool down water temps. It'd get you the best of both worlds, a cold CPU and a cold GPU.

Good advice. I am going to place a Swiftech MCR80-F 80mm Radiator in line with the system. Though not as large as my ProCombo setup, I think it should definitely help out. What do you think? This plus lapping the cpu should get my temps where they should be. I do not have room for another ProCombo.

Any suggestions on the line layout?

Thinking of:

Pump to Swiftech 80mm radiator-cpu-peltier vga-ProCombo radiator-pump? Or should I connect both radiators together such as pump-cpu-peltier vga-procombo-swiftech radiator-pump?

If this does not work out, then I will dump the peltier unit. Got to give it one last try.

thank you

How well that would work is going to depend on your water temp.
