View Full Version : my Vapo/AMD Heatspreader

I made this a few weeks back for use with my vapochill since the vapo was fairly notorious for shaving edges and corners off of AMD CPUs.
it is pure silver and it allows good contact with the evap on the vapo.
it might be because the shim helps the evap mate up better with the core or it might be the increased surface area but so far it seems to run a few degrees cooler with the shim than it did without it. it makes reinstalling the evap onto the core hella easy -- I can put it together almost as fast as slapping on a regular socket a hsf with no damage.

well worth the effort if you are using a vapochill on an AMD cpu.

you should make one for me:), I'll pay for that
Looks good from here. I'd Show asetek on the vapochill forums.
Who knows maybe they can start making those with the AMD cpu kits so the risk of killing your chip would be lowered...

the only problem right now is that it pretty much has to be hand fit to the core of the cpu....but i think i have figured out a way around that.
I am going to call the supplier and see what sizes I can get the pure silver sheeting in tomorrow - the piece I initially used was way too thick and I lost most of the skin on my finger tips while lapping it down to the right thickness. :doh:
if I remember the listings in the catalog correctly, there are several thinner types that would make the process much easier. I am going to check with a couple of the local machine shops tomorrow and see what they will charge to machine some out -- cutting these with the old trusty dremel fiber-reinforced cutoff wheel and then doing the final fitting with a needle file is way too much of a pain in the arse (although it did knock the rust off of some of the old pistolsmithing skills).
if anyone around here can machine them down to a thousandth of an inch or so, that should be tight enough to get the same results. :D

I should be getting a vapochill PE in a few weeks, so i will be making a shim like yours out of brass (my dad has sheets of different thicknesses of brass, so that is what i will be using).
Thanks for posting it here, otherwise i wouldn't have thought of making one.

Hey guys,
Vapochill includes, for super cheap, or even free, a shim for the amd processor thats made of acrylic plastic that really works well.
Even the prometeia includes a nice one (same). The major benefit being that plastic is non conductive...which is handy with the bridges they fit around on the processor.

yeah, the one included with the vapo ain't bad but it seems to cost you a few degrees. That is why I made mine out of silver -- I was aiming for mega-thermal transfer.
as far as the electrical conductivity goes, it isnt a problem if you cut the shim correctly. You can also add a coat or two of acrylic conformal coating over the bridges, etc. as a backup measure.
Hi Weapon :)
Could you please write some "How-To" on building this, cuz I got a Vapo too and don't wanna break my Tbred CPU core...
Thanxs in advance ;)

yeah -- I suppose I can make a how-to. I have some more silver stock coming in this week (slightly different thickess than the 1st batch) -- I will break out the nikon and the calipers and draw up the process. There really isnt that much to it make one after you get the measurements down.

Thanx man, that would be nice of you :toast:
I wanna put the Vapo on my 1700+ or whatever I got in the next few weeks..... but breaking cores ain't my rule of life :cool:

they tend to do something more along the lines of shearing off one of the edges or corners of the core than giving a flat out broken core. :eek:
enough to annoy the h311 out of you without totally ruining the CPU...
Weapon, anything new about the HS and the "How-to"? :)

sorry about the h311a delay TodB -- my job kicked into overdrive (sometimes I really hate being an attorney :mad: ) and my ISP is telling me that I have already sucked up all of my webspace. I am checking on hosting tomorrow. with any luck, I should be able to get the how-to up soon.
I have some others that I have to put up as well -- I owe a vapochill mod how-to to several of the peepz in VR-Zone forums as well as a heatercore conversion how-to and at least a few pics of my new waterblock design... one of these days I will learn to take these one project at a time. nah. that wouldnt be as much fun.
Well I'll wait dude, no problem....
I could host your stuff, but not sure if you'll be able to see them online if they are here in BG - we're like "country restricted" :)
Anyway - will be looking forward for your how-to.. :toast:

Weapon,
How about a silver shim for the Prommie? The one that came with it does not last thru several change outs. Would the one for the Vapo work?
Thanks :D

it should work on just about any socket a mounting system - it is actually a very small shim that frames the processor in silver.
I tried to make it to where it would proctect the CPU but not screw up the insulation design of the vapochill -- the outer seal on the evap doesnt give you a lot of room to play with -- if it extends beyond the insulation on any of the edges, the silver will collect moisture almost instantly unless extra insulation is added to it. Silver conducts cold as well as it conducts heat -- after cutting it, I can confirm how well it moves heat around. I ended up with a nice burn blister on my finger when the entire piece I was cutting heated up so quickly that some skin got cooked -- that was about an 8 inch length of silver and I was making less than a one inch cut. So, I figured that a nice, compact shim that could be easily sealed under the evap was the best way to go.
I have lightly tested one with a waterblock and also with a swiftech 462 just to see if it would interfere with the cooling of either. If anything, it seems to get a degree or two better temps with the shim. an amd shim that doesnt screw up cooling :D
Hey man, what's up with the How-To? :)
My AMD Kit is comming today and I wanna make something to protect that core... don't wanna break my good 1700+.... :rolleyes:

ack! almost let this one die.
I finally found a machine shop that would make them to my specs at a reasonable price. - they will be copper 110 instead of silver as I did a little testing and on a piece this small, there is almost no difference.
details to follow soon.
btw, would one that is a little oversized requiring a little hand fitting + better end performance be the way to go or should I go with a drop-on job that has slightly lower performance?
lol...prolly the wrong forum to ask that question. :D

Well, I ended up getting Baker's newest larger evap with 4 mounting holes for my prommie...I would rather have larger area and better performance.

yeah, they come with shims but they are plastic and they tend to cost you a few degrees - the reason mine was initially made out of silver was to avoid that. If my temp gauges are not lying to me, the metal shims can improve cooling by a couple of degrees when they are mounted correctly. The plastics ones also tend to get a little deformed after a few change-outs. additionally, not everyone has a vapochill - these will work with almost any evaporator and they also will work with waterblocks or heatsinks.

It isn't so much a matter of area - the outer dimensions are not the problem. It is a more of how tight of a fit you want around the edges of the core and whether you want the thickness to be just right. The other dimension that might require some tweaking is the thickness. The AMD cores, just like any other part, have a max and min allowable range for that part of the chip. That includes the height of the core. Having the thickness just right helps protect the edges of the core and it helps align the evaporator onto the CPU. :)
I am waiting on a test sample - as soon as I give it the eye and make sure they are making them to spec, I will place an order for a decent number of them. I'll put up another post as soon as I get some more info. :)
