Dtek whitewater to cascade upgrade results

Ruiner · 10-02-2003, 04:58 PM

I had ordered my Dtek WW and Cascade at the same time and of course the WW arrived first. With it in my rig, my cpu temps were 50C folding, and 54C under cpuburn. These temps were after lapping (before they were 2C higher).

My cascade arrived and I sold the WW (for what I paid).
With in in the rig now, my temps are identical to the lapped WW. The coat of artic alumina is only a day old, so temps may drop a bit.

My radiator cooling (shrouded, rheovolted panaflo m1a on a heatercore) needs work....my water temp is 14C above ambient air. I may upgrade to a push/pull, since I want to keep it quiet.

Strangely, my water temp with the PC/fans off but pump on is still 13C above ambient air (8C over case air). could the Eheim 1048 be heating the water that much?

Wow, an ambient/water temp differential of 14C is pretty high... Try to get that way down, to around 5 - 7C above ambient. Also, your pump hanging off the WB is not a good thing.

Cathar · 10-02-2003, 08:05 PM

It sure looks like the waterblock is basically supporting the weight of the Eheim pump as it hangs in mid-air like it is. This is exceptionally bad in terms of getting a proper even mount of the waterblock against the CPU.

You tried a few remounts? Ambient temperature was the same before and after?

Oh, and yes, without fans and with fairly restricted radiator air-flow, ~8C above case temperatures for the water does sound quite plausible for a 1048 pump to heat the water by.

Ruiner · 10-02-2003, 09:14 PM

It looks that way, but there really isn't any tension on the hose at that point. the pump is up on it's edge, on a sponge. The hose lengths are a bit different from the WW setup, so it will be corrected. Most of the support is on the inlet hose from the rad.

Ambient temp is the same. No remounts yet.

Redo the hosing and remount the block - even having a smidgen of pressure like that can send your temps up - when i had my mcw50 hanging in mid air, my temps went up by like 5c for no reason - they are very fickle things

whats a Cathar "Little Arse" rad?

I used to make and sell custom radiators over a year ago. It's a heater-core radiator from a Ford Festiva. Imagine something that's midway between a DTek Pro core, and a Black Ice Xtreme, in size. Cooling performance is, I estimate, to be around 90% as effective as a DTel Pro core given the same fan.

cathar said it best, also - it is about 80% of the size of a 87' camry heatercore, it's doing it's job admirably atm :P

still waiting to see if the temps were fixed.

Can we have an update?

Do you really have to have a large pump to get good numbers? What if you only had a small one, would these blocks still beat the maze4?

Ruiner · 10-20-2003, 07:59 PM

Sorry for the lack of updates. I disassembled my cooling rig to redo the tubing and radiator (to add a 'pusher' fan). I also have a swifty gpu block on the way.
When it is back together, I may be able to bum some Ceramique from a friend for the Cascade.

I did find out that my water temp thermistor was bad. It was reading about 5C too hot (the JB weld insulation partly wore away). My water temps were therefore only about 8C above ambient air.
That makes the reported cpu temp/water gradient about 15C.

Cathar mentioned in another thread that the cascade has allowed better overclocks despite no (reported) temp improvements in other (I think primarily P4) rigs. I may try to push the OC a bit.

I'm curious to see how much heat the geforce4600 will add to the circuit. It certainly heats up my 1U copper HSF well.

My heater core is 5 x 5.5 x 1.5" (not including the end tanks) by the way....maybe too small.

I would say a bigger pump is what is needed. I noticed my 1050 got much hotter when I put in my WW over how it was with a TC-4 rev2. The casade most likely creates the same pressure as the WW.

Ruiner · 10-26-2003, 02:15 PM

This is the new rig. It is much quieter. With the case open, my temps are the same as before, even with the swifty mcw50 gpu block in the loop. With the case closed (including intake filters....I have a long-haired cat), reported cpu temp is 53C, but the PC is near silent.
Running the rad fans up drop temps about 2.5C.

The reservoir is certainly easier to fill/bleed than the old t-tube.

Case interior and water temps are about 7C above ambient.

These temps are with artic alumina and a re-mounted cascade. I'll probably have the Ceramique this week, but I doubt it will matter.
