Vapochill is insane...

I was reading this thing on Vapochill cooling systems... they're insane.... it goes ont he bottom / top of your computer and keeps the cpu at constant negative temperatures.. even a prescott and %100 load it was still -10C ... i am amazed... although they are several hundred dollars.. perhaps when i'm filthy rich i'll buy one

Wow, that is amazing, i knew they were good, but not that good!

Me want bad!

they are really over the top. and they are more than just a few hundred dollars. Closer to a grand. If I wanted to go for benchmark records then I would get one but for everyday use they are not practical.

I wish I had one of those to play with but they really aren't needed. Most of us can play games without any lag and insane overclocks arent' needed.

Maybe we could all chip in for a record setting PC and vapochill?

Yes, that would be most excellent. We could get a prescott too

hey hey i never said it was needed.. btu be honest if you won the lotto would not get the most ANALY PENETRATING (pardon my language) rig out there? i'm talking the whole shabam, freezer system and all

Ok, guys, been foolowing the thread since yesterday, but I need to add somthing here. If you can sort out the power requirements I would build this:

1 water block
1 drift 0.8 TEC *optional, water block may be all you need*
pump / resovior
a few meters of 9mm copper pipe
1 second hand fridge freezer (the type with small freezer compartment in the top of fridge and uses this to cool fridge.) a small table top size would be good.
length of suitable tubing
Antifreeze

plan:

Attach water block and pelt, make sure pelt is attached to cpu with a copper or aluminium block to even out the temps. seal to mother board using expandable foam around the block and on the back of the board. this is easy to cut with a sharpish knife. this seals out any condesation. *does make a mess on the MB, but block and chip can be removed. use petrolium jelly to stop foam sticking to edge of cpu and socket. just a thin smear will be enough.*

Attach tubing to block, use pre-formed foam insulation used for heating systems or water tanks to insulate the tubing.

Drill 2 holes into fridge door and push tubing through. would be better to attach 2 self sealing push fit connectors on the door.

Connect one end of the tubing to the pump and res.

Use a reasonable hard tube or wine bottle to start bending the copper pipe around, now keep spiraling this round it's self until it is at least big enough to just nearly touch the sides of the freezer compartment. this should be a flat spiral.

Attach pipe to tubing, place in freezer compartment. door of compartment may need to be drilled. the frost that bilds up in the freezer should be left as this helps absorb some of the heat (I found this to work best for me).

fill with water and antifreeze suitable for -40 deg c

start the fridge and let it chill. let system cool for 12 hours or so until is is completly cooled down. start yoour system and start to overclock. let each speed run for at least 6hours under full load to make sure it's stable.

Voilla you have a MUCH CHEAPER vapochill style cooler., you could insert the mother board in the frindge. I managed to attach one to the door. no need to worry about condensation, will be sucked up by freezer's evaporator and stick to copper pipe. a good build up REALLY improves the cooler. not good idea to open door while system on as condensation WILL form on the cold surfaces.

The bigger the fridge the more cooling it will have. try going to a repair shop and see if they would be willing to build the compressor, evaporator and condensor into a smaller package for you. if they service fridges, chances are they will help.

This system worked for me, got VERY good temps, -40 is possable using the pelt at 18V

dont let your system idle though as the temps WILL drop -68 will damage your TEC and cpu!

too much of a mod
lol

i got tired of reading... ill get through it sometime today...

ha.....great idea SS......but that means youd have to keep it under LOAD at all times..........too much wear and tear you think????

Nah, I would'nt worry about the load, the heat would be the problem with the load. with the chiller ther would be little or no heat to worry about.

Overclocking is all about cooling. Your cpu will go much faster on the same voltage if cooled properly and increase the FSB or multiplier. I buit a system a while back that would monitor it's self and automatically heat up the cpu if too cold and slow the core if too hot. system also had the ability to shut the system down and power off if the cpu temps rose beyond normal and aproched the point at which it crashed. this was usually caused by not enough antifreeze and the pipes becoming frozen. the water block would start getting hotter as no coolant was flowing. I made this due to haveing a previous rig blow the pvc tubing off the waterblock and start ejecting boiling water and steam due to the OCed chip and 175W peltier.
All of that control is ready available on the net (mother board monitor and plugins). not hard to set up and gives you peace of mind if you leave the system unattended.

Incidently I have hosed down 3 systems due to leaks or pipes coming loose, I only ever damaged 1 card, a Voodoo Banshe that just happend to be too close the the leak, even though the rest of the MB and cards were soaked for several hours while the machine was on.
card could have been fixed but it was'nt worth it ( 1 damaged track going to the edge connector).

Good idea but ou don't think condensation would be an issue?

condensation taken care of by the closed cell expanding foam, comes in a can. it's used to plug holes in walls. waterproof!
If the machine is built into the fridge then there is no problem as the computer will be hotter than the air surrounding it. condensation will only form on cooler surfaces. the eveaporator of the fridge is MUCH colder, about -38deg C while running. thats assuming it's a newer generation of fridge using R13a refrigerant.

The Vapochill uses the exact same equiptment as a fridge, only diference is the evaporator. this is similar to a waterblock and is attached directly to the back of the CPU. CPU is then encased in closed cell foam inside a small housing and this is used to attach the device to the mother board.

You can build your own vapochill using an old computer case and a few old fridge parts *warning do not attempt if you are not familiar with refridgerants and handling procedures* - get a pro to fill it up for you. The pipes are usually copper and can be easily soldered together, just build your own and take it to a service center and they can run a test to make sure is sealed and can then re-fill the compressor. whole thing should'nt cost much, about $50 or so.

Got ya. Yeah, I really didn't bother to read about the foam when you said it earlier.

Sorry but one more question. . . how well of an insulater is that foam? would it let enough cool . . . molecules get towards the computer itself? . . . especially after it has been under load for a while?

The idea for the foam is to insulate the Evaporator attached to the back of the CPU (same as a heatsink) from the surrounding air, the foam is liquid so it flows into all the gaps which then sets solid and stops condensation on the CPU and block. The foam also stops the heat of the surrounding air being absorbed into the block / CPU and increasing the heat needed to be transfered.

The CPU and evaporator are connected by a layer of thermal grease, same as a heatsink setup

The Foam is a good insulator, can be used to Insulate the copper pipes to stop frost forming there.

OK. Its making a little more sense now. This would definately be worth a shot!

Cool.... very interesting, my dads and engineer, he has expericene with all kind of machinery even fridges, i think he has all sorts of spare parts. *devillishly rubbing hands together*

yeah that sounds like fun, maybe I'll go to a fridge repair shop and see if I can find the stuff I need from an old fridge.
