View Full Version : Vapochill Mod (remove heat pads)
Hey bros...I thought I'd post pics of what I'm up to. I am sick and tired of not getting the premo temps out of my premo-spendy-rig. As you can see below the Ol' Vapochill doesn't get as good temps as you might think. I know, I know the Prometia is posed to be Da Bomb. But here I am with just a measly old Vapo. Anyway, like any good OC'er I want to squeeze every-last-drop of performance out of my setup. The Vapo people recommend using two heating elements to combat the ever present "evil condensation." Yes you heard me right, two heating elements: one on top of the cpu and one directly behind it on the mobo. (I don't think the Prometia has this) Any one knows that this will decrease any cool temp yeilds that one might hope for. So...I am replacing the back heating element with a good coating of "Dow Corning" sealant aka high/low temp resistent silocone. I know many people use this with pelts and get great results and they don't use heating elements either...so neither will I. This is a project in motion and right now I am waiting for the silocone to dry. So I will post pics of how far I have gotten. krag

Does Dow Corning come in a spray? and if it does do you know where I can get some.

i have always wondered why they used those... and what were your before and after temps of the cpu at what speed and wattage???
Not to shabby :eek:
Insulate the socket, use dialectric grease and you can ditch the heaters. Dangerden or McMastercar have excelent closed cell foam for sealing sockets off.

Krag-I had the mod remove all the clutter I inadvertantly added to your thread--sorry about that(I hope he didn't remove too much). Hopefully this bump will help.
Why are all of my posted pics been deleted? Ans alot of other replies have been deleted also!
Man what a drag my thread has been totaly gutted!! I wanted to send it to a buddy of mine who is having problems with his Vapo. I guess that won't happen. But I will post some results here in a little bit about my new temps.

Why don't you re-post the pics?
THis is the silicone after it has been applied to the back of my mobo. I used up all that I had and concentrated on the area directly behind the cpu and especially the raw uncovered contacts. Do you see where I got kind of sloppy? That is where the solder was not covered with the typical mobo sealant, you know the thin plastic like covering that is on 99% of the mobo and it's traces. tHese were exposed and raw, a perfect place for condensation to develop and cause havoc.
Shes ready to slap in! I know the Hardcano 2 won't do a good job ofv cooling my hd but I wanted it mainly for the temp probes. I think my Asus Probe program is off. Besides I don't trust software over hardware.
My rig is down for a little while. THe batteries that came with the hardcano were as dead as a doornail. My old lady is at the store buying some for even as we speak. So as soon as I get the batteries in I am gonna post some new temps. krag

Even though your Hardcano might not cool off your HD as much as you'd want, I think that by bringing in more cool air to your case your temps might drop a little--besides, it'll dress up the front of your case considerably!! Your on die temp sensor that Asus has can be more accurate than the insocket ones most of us have, but I'm with you in that an external probe can help verify what your temps really are. Are these probes small enough to fit under your HS and touch the CPU?
This is what my Asus probe temps are right now with the one remaining heating pad.
This is my preliminary hardcano 2 results. The right temp display is my cpu and the left is my north bridge. I don't think the hardcano 2 reads temps in the -0c range. Cause when I turn on my rig the temp climbs to 33c and then when the Vapo kicks in the temps drop all the way to 0c and then the display shows nothing but "LLL". Man this is a total bummer cause this was the main reason why I BOUGHT THIS THING IN THE FIRST PLAC EWAS TO MONITOR MY CPU TEMPS!!! There is no degree range mentioned on the package or at the website that i purchased it from. A lot of work for NOTHIN'! I have the temp sensor right on the top of the cpu core, its off to the side, not where the copper evaporator plug will touch it but where it will be covered with the foam that surrounds it. If you look at my pic/post about the top heating element (heating pad #1) you can see where the copper plug left a circular indentation in the AS3.
What do you guys think I should do now?
This is 15 min. after I unplugged the other heating element. I only gained 2c. Oh well...better than nothin'.

hey bud, 2 questions: first, is it needed to go as far left with the silicone as you did? and second, is it smart to use as3 instead of the goo that comes with the vapo?:D
It might not be needed to go as far left as I did, but I couldn't let all of that raw metal go untreated. As for the AS3 I just put it on the core of the Northy and I put the white goop in the pinout holes and sockett plug. The Asetek people say the white goop has superior cooling capabilities. But I just do not see how it can beat 99% micronized silver. And besides, how can frozen metal do any worse than frozen goop?
I don't know if your mobo has those long strips of exposed metal/solder. If it doesn't I wouldn't go that far just cover the back part of the cpu.

Her is a temp reading at load. This was taken 2 seconds after playing SOF 2 for 15min.
cpu @ 3011mhz
v-core at 1.6 in bios Asus Probe says 1.65
Ambient temp is 23c
This beats my pre-mod idle temps by 6c. Previous load temps were 20c.

where did you get the chipset cooler?
I just typed in "Thermaltake Tiger 1" in the pricewatch search box and bought the cheapest one. It is the only aftermarket Intel Northbridge chipset cooler that i know of. There might be others but I don't know of any that will use the little hook clips to fasten it. I guess you could use just about any chipset cooler if don't mind using the epoxy stuff. But personally..I mind.

you could alwways be inventive and make your own little clips out of some scrap alu or plastic or something.

I have a AMD XP cooled with a Vapochill using a Delta fan as my radiator fan. Works very nice.
The guy from OC-Shop.com here in the Netherlands kinda adviced my not to use the heat pad as the AMD's get so hot there is no condensation.
Anyways, my idle temp is 21C right now while the chiller is at -9C - -10C. load temp is about 24C.
The Delta runs at about 2100rpm right now and that is very nice in terms of noise level. running at 2400rpm the chiller get's to about -12C and lowering the idle temp to about 19C and load temp about 22c - 23C.
2400rpm is much more noise therefor I chose not to have my temp's that low. I do try to keep the chiller at about -10C. So when I overclock further I may need to speed up the fan a bit more. But that's ok :)

I can't visualize any picture, is this my browser having trouble?
