Bad Temps

Deke_Kun · 01-06-2003, 01:25 AM

Ok, just put together my first WC loop. I'll list components and detail setup first, then talk about the problem.

Innovatek Waterblock Rev3
Single Innovatek Radiator w/ 64CFM Globalwin 120mm Fan sucking.
600L/h sumbergible pump, running in a small 3"x2" tub because it wouldnt fit in the reservoir.
Innovatek Tank-O-Matic Reservoir
Innovatek Flow-O-Matic Flowmeter
All on 3/8th"ID tubing (8mm).

All hooked up and running, on an Athlon XP 2000+ at stock speed/voltage. Was getting about 50C on half-decent air cooling, room temp is about 30-32C. Case temp is 34C.

With this equipment, CPU temp is 46C under full load. The water is warming up, without a thermometer to check, I would guess its at about 35C or so, and the tanks at the top/bottom of the rad are slightly warm, so the water seems to be getting warm. But still, the CPU temp is quite high. Or at least I feel it is. $250 worth of watercooling equipment, and only getting AX7 temps? Doesnt sound right to me.

I've checked that the waterblock is clamped tightly, and it is. I noticed it is able to be clamped tighter when it has heated up, which I guess is logical.

Any thoughts on these temps? Is this equipment that crap? Have I done something stupid?

//EDIT - Forgot to say what the CPU temp was. GAH! Cpu temp seems to be idling around 46-47C.

it idles at 46-7 and at full load is 46?

how long did you let it go at full load?

how long did you let it idle?

cuz there should be a difference in full load and idle temps.

also, did you lap the block at all?

what thermal compound are you using?

Deke_Kun · 01-06-2003, 07:04 AM

Sorry 46C is full load temp. Full load was run for about 24hours solid, temp stayed the same. Idle was about 42C, depending on ambient temp (day/night).

Waterblock was not lapped, the surface it had already was mirror-smooth, so I presumed lapping would not be needed.

Thermal Compound is Arctic Silver 3. A thin layer, same as I use for HSFs.

If your water temp is indeed 35C (you should find a way to measure it), then your problem is the cooling part of the loop, i.e. the rad and fan.

That fan might give you 64 cfm, but only with no restriction, which will make it quite low. I don't know anything about the rad: got a pic?

Otherwise, the Innovatech block is one of the best ones out there.

Deke_Kun · 01-06-2003, 09:08 AM

For pics, check here . They have nicer camera's than I do

I'll have to see if I can find a temperature probe that I can stick in the water, unfortunatly, its a closed loop (despite the reservoir) so I cannot actually open it up with the loop running, without it leaking everywhere. Opening the res causes the pressure to break and the res tries to overflow :/ It only works when the res is tightly capped so the pressure is maintained through the whole system. I will do my best to get a water temperature reading.

As for the fan, I know it sucks. I'm trying to obtain a replacement, but have had to order a 120CFM sunon, which will take a week. And even then, to be honest, I dont feel that the water can be much more than a few degrees above ambient air temperature, so I don't know that it will solve my problem.

Maybe there's a way that you could seal your loop, just so that you could drop a small thermometer in the res, then close it back up?

That rad looks awfully small, and restrictive (3/8 fittings/tubing?).

The simple things that you can do right now, is check if there's any way you can add to the clamping pressure on the CPU (but be careful!). It won't solve your cooling problem though.

How do you measure that CPU temp? From which mobo?

Do you have any idea what kind of flow rate you are getting?

UnloadeD · 01-06-2003, 04:21 PM

Your room temp is toooo hot, 30-32C! Open a window, turn on the AC! Inside of my case isn't that hot. With the small rad and the warm room temps that's prolly the best you're gonna do. I realize it's summer time down there, how's the humidity? If its not real high you might consider setting up a bong to get ya thru the hot part of the year. Let us know what ya decide to do and how it works for ya. G'day mate! lol

peace.

edit: Remember that with the best rad/fan combo the best you can possibly do is get near ambient water temps. With the best block/flow/pump combo the best you can hope for is to get the cpu near water temps. Taking these into account along with the facts that you have a) high ambeint temps b) small rad c) low cfm fan d) small pump e) small tubing f) block is debateable g) a hot cpu. Taking all of this into account, the system isn't doing too bad of a job. It's the high ambient temps that are really hurting the most because all else hinges on that. If you had the best water setup available, I'd guestimate you'd be lucky to get temps around 40C.

Deke_Kun · 01-06-2003, 06:32 PM

Thats in the middle of the day. I just woke up, and ambient temp now is about 27C, CPU is at 43C. That's not bad I think. I don't have AC, all I have is a fan sitting in a windows trying to circulate air, but when the days get hot, all it can really do is circulate hot air.

CPU temp is measured using in-socket diode (eww) on an 8K5A2+.

The entire system is on 3/8ths tubings, the rad isnt special in that regard.

As for flow rate, I have the little flow-meter in the system which reports a value to the motherboard header. Only, I have no idea what the value it reports is. The number is 3700ish, will fluctuage between 3705 and 3792. But if you know what flow-rate that equals, please do tell me.

I'll have to find a small thermometer first, and then I'll try to get a water-temperature reading. So far I've just been using the touch-the-tubing/res method to guage water temp.

Waterblock is on as tight as it will go. Any tighter and I'm going to start risking pulling my socket off. I was able to bring temps down from 49-46C (in the hot part of the day) by tightening the block. But I really dont think it will go any further.

A bong is a bit more than I can handle I think. Especially seeing as I'm three-floors up. So I just hope to get this waterkit working.

I know the fan sucks, like I said, it is being replaced, just wont be until friday/monday. Hopefully doubling the CFM going through the rad will decrease water-temps.

Ok, I think I got it all.
