Watercooling, all arrived and ready to be installed!!

i may be being rather silly in asking this but wouldnt apoxy not conduct the heat very well and infact a heat compound would be better ? (please correct if i am wrong)

The epoxy is used as a gluing agent, and the Arctic Silver product is designed to be mixed with another of their thermal pastes so it is just strong enough to hold and is also still a great heat conductor but it is permanent, unless you dilute it more than the recommended 50/50. Most people seem to recommend 75/25 or some use a small amount of glue in the corner of the RAMsink and use thermal paste in the centre which makes contact with the RAM chip, which is apparently easier to get off without ripping off the RAM chip from the PCB.
 
thats what I plan to do, just a small dab to hold the thing there, and I will use some arctic ceramique - think its "stickability" is a bit better than the AS5.

Well Im up and running (sans Ramsinks) Ive ordered some epoxy if I do decide to install them....

what can I say, Im really impressed with the system - its dead quiet, the only thing I can hear now is the whurr of my Raptor and that's in a silentmaxx enclosure anyway!!

temps are very impressive:

(CPU - idle)The Eudemon's thermal sensor is reading 20'c
(CPU - idle)Everest is reading 19'c
(CPU - load)The Eudemon's thermal sensor is reading 25'c
(CPU - load)Everest is reading 24'c

(GFX - idle)ATi Tool + Overdrive both reading 32'c
(GFX - load)ATi Tool + Overdrive both reading 36'c

The GFX memory is currently at 37'c idle and 40'c load, this is without the ramsinks, so hopefully when they are on they should make a difference - also when I install them I will attach a thermal probe to the GFX core.

So what do you think?

Your PC is in either a fridge or your sensors are way wrong!
however your GFX sounds about right. :)

Impressive !

Inaccurate !

No , seriously , nice set up.

But those CPU temp readings cannot be right ??

Check with a probe , unless you live in Iceland ( with a window open and a bloody strong wind ! ) your CPU can't be running at 19 degrees idle.

Unless , of course , you have found the dream combination , in which case I'll get me cheque book out and buy it from you ;)

Cheers,

Mark

that is a thermal probe.

since Ive moved the PC upstairs (those initial temps were downstairs where its colder) Im getting 25' idle on the CPU and 38' idle on the GFX, but Ive overclocked the GFX card to 700/800 at 1.425v put back at stock that would be more like 34-35'
 
Hi , sounds a nice setup , i had the same problem with the ram sinks although once they ran for a while the pads seem to take hold , one came off the composite chip, the extra one on the master card ,and it didnt like it ,it did a few strange things so now i have a vantec fan card blowing down on each gfx , as for the temps even with just my cpu being cooled on its own at the moment as i am changing from 1800- 1900 gfx's i have 34 degrees.

Thats what Everest is reading for my CPU temp, and the thermal sensor from my Eudemon unit reads 20.

Room Temerpature is around 19-20, so it is cooling ambient.

Dont insinuate that Im not telling the truth please.
 
My cpu starts idle on a cold day at about 20-25 so this isn't that unbelievable especially if your window has been open all day and you're w/c's better than mine. As I said before I really wouldn't bother with the Ramsinks.

thats after about an hour and three quaters of cs source.

again the thermal probe on the eudemon is 1 degree warmer.

yeah dunno about the ramsinks yet, Im not decided - the temps on the card even now the memory is overclocked are still reasonable - 44' after that gaming session.
 
I don't see the ambient temp anywhere :confused:

Oh, he said room temperature is 20, which means his sensors are probably just a little off, be it his room sensor or his PC sensors, of both :p
 
since Ive been back in, room temperature has gone up to 25' as I closed the window and obviously my body heat has warmed the area up a bit.

Im not lying, ffs.
 
why cant it be? both the Mobo sensor, and the sensor from the unit read the same, bar a degree.

as we speak room temperature is 25' and the CPU sensor reads 25'

its not impossible, as its fact and Im looking right at it now.

wish I had my digi cam.
 
Heatsink C/W is measured by the following formula:

Delta = CPU temp - Ambient Temp
C/W = Delta / CPU Watts
Interpreting C/W: For every watt the CPU radiates, the heatsink will cool the core by the (C/W x watts) plus ambient temp.


For example, at an ambient temp of 25 C, a C/W of 0.25 with a CPU radiating 50 watts means that the CPU temp will be 50 x 0.25 = 12.5 C over ambient temp, or 37.5 C. The lower the C/W, the better.
 
Ah, ok. Sorry for some reasoin I thought you'd just said that your CPU was 20 when the room was at 25. No that's fine. That loop must be pretty sweet to stick at ambient temps constantly! Nice one :)
 
yeah whatever.

Im basing this on the fact my mobo sensor reads one temp, and an additional one glued to the side of the CPU IHS reads 1 degree warmer than the mobo.

I have another sensor monitoring case temps and another monitoring the outside temp.
