asetek vapochill case, any one used one?

buttkinz · 7 Dec 2009 at 11:06

I'v just bought a asetek vapochill case (yet another christmas present

). Has anyone had any experience with them? the evaporator (?) head mounting is for the P4 and older athlon chips, although the chap im getting it off sais with a little DIY it should fit the socket 775, has anyone done this before?
Also what sort of insulation etc should i buy in the mean time before it arrives so i dont get any condensation wrecking the other components?

sorry about all the questions, cant seem to find much info on the cases or use of them, theres a pic below to show the case

I thinik from the information its the asetek vapochill PE

I'm not too familiar with the vapo's mounting mechanism but bearing in mind you will need to achieve an airtight seal around the cpu "a little DIY" may be an understatement.

For insulation you would generally use:-

some dielectric grase in the socket
PCB lacquer on the rear of the motherboard
clear nail varnish on any capacitors etc near the socket
Neoprene cut to fit round the socket (self adhesive sheet neoprene is what you want)
Some seal string if you were using a non custom prommie head

load of info can be found here

specifically somethign about making custom mounts here

I'd also be wary of a non-customised phase unit's capacity for cooling a modern overclcoked cpu - how much is it costing you?

hi, thanks for the reply

i paid £57 for the unit, i thought it was a bargain at that lol

does customisation cost a great deal? is it just a regas with different refridgerant or is there more to it?

As a HVAC engineer I'd seriously suggest not bodging the socket kit unless you want frozen PCB goodness

generally you would get a regass, new head and mounting mechanism, probably a desuperheater coil added and maybe a bigger condenser

I had my prommie done a couple of years back and it was around £250 if I remember correctly. The thing is finding someone good who can do it in the UK. Gray Mole (hi if you read this) in newcastle was the main man and who did mine but I'm not sure if he's still doing it. Best to post on the extreme systems forum I linked to and see who is available

Aren't these rather a lot more noisy than they are worth?

They are noisy but quite low frequency - I found air cooling woth noisy fans worse but it has been ages since I did any air cooling.

If you want that extra couple of hundred Hz over good watercooling they are worth it

Personally don't run mine anymore as my cpu was pretty old

Waste of £57 to be honest, it's going to be rubbish on a current S775 CPU.

bifday2k · 7 Dec 2009 at 22:28

Not really just google for this "Asetek Vapochill Socket kit (LS, XEII) Intel LGA775 " that kit costs £75 and allows u to adapt it for S775, ofcourse if u know how to or find someone that can.

Totally agree.

The PE's were designed for use with single core CPU's.
They are charged with the wrong gas, too small a condensor and not tuned for dual cores. In fact if you were to run it on a dual core, you would get massive "flood back" to the compressor. The result of which could be very dangerous.

For the time they were made, they were a good introduction to phase for peeps that hadn't used phase before. But with todays cpu's, they are just worthless scrap i'm afraid.

Ah then if that is the case, ignore what i said about the adapter kit then.

Not so sure about getting flood back, if the CPU is giving out more heat than initially designed for then all of the refrigerant will evaporate anyway, your system performance will just suffer as it may be superheated.

Ovr · 8 Dec 2009 at 11:08

Oh and you can't get liquid refrigerant going back to the compressor anyway as the expansion valve will not allow it.

Your just gonna end up with a hotter chip; what's the power of the compressor? The type of refrigerant won't make much difference if your compressor is undersized anyway.

Have a read of this please.

As you can see "Floodback" has nothing to do with an expansion valve.
A basic understanding of phase would have told you that anyway :rolleyes:

Lmao, hahah just cried on my floor ;( You won't get liquid slugs on a vapo. The expansion valve ensures that no liquid gets back to the compressor as...you've guessed it, gas occupies more space than liquid.

Ba boom tsh.

I take it you didn't bother to read the link then ?

I did. I totally agree that liquid going back to the compressor in slugs is not a good thing and it will mangle it, but in this case that won't happen.

The refrigerant flow is balanced to ensure complete superheating to allow all of to evaporate.

cheers for the heads up guys, Im not allowed it till christmas (cant con the inlaws

) but I tested it with an old 3ghz p4 when it arrived to check it was working, took it to 4ghz and it seems to run nice and cool, still around -10 to -11 under a quick load test, surely this will be better than my current watercooling with a modern dual core??

It isn't, its going to be loud, hot and horrible.

No, because a modern dual core would be at +20c/+30c. The phase wouldn't be able to hold it for very long either, so the temps would just keep going up and up with the predictable result.
