Water cooling Help

Smirnoff · 16 Feb 2008 at 00:40

today. As for the other stuff i was thinking about the following

Laing DDC 3.1 Pro with Plexitop
D-TEK FuZion CPU Block
Swiftech MCRES-Micro Watercooling Resevoir

Bit unsure on what brand of tubing to use, Seems to be some very expence stuff around whats the best brand to go for ?

I take it that its best to build the loops with 1/2" barbs and tubing ?

Use metal barbs over plastic ones ?

Better to use barbs that use orings or the type that you seal with PTFE tape ?

Sorry for the stupid questions but i'd kick myself if i ordered all the wrong stuff, Thanks for any help or advice

I used Danger Den high flow 1/2" barbs with my D-Tek fuZion and Eheim 1250 pump, seems to be working nicely

So does living in the outer hebridies with a force 10 gale.

Must be quite a loop for 12C coretemp.

Matt, we love listening to you go on and on and on and on and on and on

how dare you!

weescott said:
who? what? yes anyway...to sumerise....yes the OP idea is sound.

move along...nothing to see here.

and you! how rude!

Nah, Essex innit gezzer!!
Nice and toasty here, I'm sat typing this in just a t-shirt

My computer however is freezing it's nuttz off

waterchiller or phase?

Neither, just a custom water-cooling setup and good old British weather

well then either something is being reported incorrectly or your pc was outside, those temps are impossible because ambient would need to be below 0 to get you a core temp of 4 degrees.

Yes, my PC is outdoors. Thats why the temps are so good.

true physics dont lie, not even built my first water rig and i no this to be law lol thats why i said that he must be in the artic circle its just not right to have them temps, and with you saying your in a tshirt means your ambient must be high so you can have low temps like that

you serious so when the temps outside drop even more and you get moisture inside the case and on the mobo then what ???

Been running my computers outside for a good few years now without any problems so moisture is not an issue.

Your assuming I'm located where my PC is, you know what happens when you assume!! lol

Assuming the rads outside and the PC inside, then condensation would be fun. Still even if the whole PC was outside the 6C coretemps would need about -12C, must be 30% Glycol and a really cold spot. At idle and the DTS values can be miles out at low temps wouldn't take much notice tbh.

The whole PC is outside so condensation is not an issue like I said.
Ambient temp was about -7C and I use 2 litres of fesser one cooling fluid in my loop so I'd say the coretemp readings were pretty accurate tbh give or take 1 or 2 C.

Ok, I'll assume its idle (no way thats load) the quad at half load. Just a guess at flow rates vcore etc, but a Fuzion and PA series I know.

-7 + 0.02*(75+18) + 75*(0.057 + 0.0045) = -0.5C and thats the IHS temp.

Coretemps at least 10C to 15C higher than the IHS depending on stepping. Its at least 5C out, like I said start at -12C would get there. You cant believe the DTS values they can be inaccurate at low temps. For your lower coretemps the coolant would need to be something like -10C.

Here's mine, -3 ambient, 3200GHz 1.2V

-3 + 0.017*(137+18) + 137*(0.057 + 0.0045) = -3 + 2.6 + 8.4 = 8C at IHS

For ref:

Ambient + system load (inc pump) x radiator C/W + CPU Load x (block C/W + TIM C/W)

Normal room temp at 4GHz.

22 + 0.017*(220+18) + 220*(0.057 + 0.0045) = 22 + 4 + 13.5 = 39.5C

Add between 10C to 15C for coretemps, 12C for mine.

So 51.5C

Yes , someone starts talking out of their exhaust.

Facts don't back you up , listen before you make wild claims.

Woot , does 2 litres makes it even cooler than than 1 litre :rolleyes:

You are trying to defy ambient , never been done , never will .

C4EVA · 16 Feb 2008 at 18:30

Who said I'm trying to defy ambient.
I'm just posting what coretemp says which is what everyone else does when posting about cpu temps :confused:

Ambient temp when those readings were taken with coretemp was -7C

I used 2 litres because thats what it took to fill up my loop! So have your :rolleyes:

back and jog on.

I simply said that I thought coretemp was pretty accurate considering that ambient temp was -7C, so what your saying is CORETEMP is WRONG.

so what your saying is CORETEMP is WRONG.

Its based on DTS values and an assumed starting point (Tjmax) which is incorrect, should be the factory set TCC. Unfortunately that's an unknown. Its impossible for Coretemp to give an absolute temperature and the further it is from the TCC the more potential it has to become inaccurate.

It simply doesn't follow that a 4C core temp comes from a -7C ambient using water cooling. Do the sums yourself.
