Mid 1999 we reviewed VapoChill as one of the first sites .
A lot of reviews has since that time hit the net. And all reviewers have been very
impressed by Aseteks VapoChill - except for one .........
We have had a dialogue with Asetek on how to improve the CPU kits resistance even more against condensation ,and we will here give you some tips based on our findings. These tips is fairly easy - VapoChill users should have little problems doing this,and besides these tips can be used with any supercooling setup.
CPU box :
We used ~1mm. thick aluminium tape to cover the outside of the CPU box. This will increase the resistance against condensation passing through the plastic. This is because every material -more or less- breathes (permeability).
PPGA kit improvements:
If you use a ppga kit we suggest you solder of the capacitor and move it like we have done here. (you can see that we have reconnected it using a thin cable) This condensator is touching the evaporators coolant pipe and can cause problems related to condensation. Asetek themselves has started to relocate this condensator, so the relocation might already have been done.
The back of the slotconverter can also be covered with die-electric paste* to increase resistance of the contactspoints starting to corrode (verdigris).You can also use electrical varnish instead of die-electric paste ( remember not to spray the Slot1 contact pins !)
If you want - you can also do as the water-cooling guys do : smear die-electric paste* (or you can use non-conductive thermal paste) in the bottom before you put in the insulation and all over the socket itself . Also take note that we have added die-electric paste at the CPU itself.
*die-electric paste : non-conductive silicone
We converted a Addtronics7896a cabinet (here) to house a Danfoss BD50F compressor which is more powerfull than the BD35F compressor which the VapoChill is delivered with sure not to get condensation using a compressor which is "out of spec" for th. To be 100%e CPU box we insulated the CPU box' and the evaporator hose outside with Armaflex. (Armaflex - or another brand thermal insulation- can be purchased at your local air-condition repair shop).
My personal opinion is : if you do a correct job with the installation and don't use the tilt trick / condensertrick or use software related CPU cooling to increase cooling - you will not get condensation !
But then again- I know it is very tempting to use every possibility to increase cooling to squeeze as much speed out of your processor as possible ! If you do that without taking some extra precautions you increase the possibility greatly to damage your CPU.
My advice is that if you run VapoChill and use every trick to increase cooling : follow the advices above !
Regarding polishing your CPU : based on our findings we advise not to polish the 0.18micron Intel CPU core if you use anything else than conventional air-cooling. It actually seems that condensation can pass straight trough the siliconeslug.
If you think you have additional tips that should be mentioned here - feel free to send me a mail Webmaster OcShoot
