How heavy of springs do I need to use to make sure my water-block applys even...

[Nick C]

pressure to my processor? I have to use four springs. Basicly, what I'm asking, would I get 4 - 4lb springs, or should i get 4 -16lb springs. (i wanna exert 16 lb, its in the mobo specs

Thankyou much!

i cant say for sure but i wouldnt do anything until one of the seniors here throws you some info on that. you could easily crack your chip if not careful. someone will give ya the right steps.
try to include your system specs in your profile so we can help u quicker and youll be happier :)
welcome and good luck bro!

I thought about using springs but chose to have nuts tighten it down instead. That way I know it's getting constant pressure and can't give. The only bad thing is that you take the chance of crushing the core that way. I had to modify a PIII Waterblock to fit on my A7A & 1.2 gig T-Bird. Right now I have a piece of metal going across the block diagonally to 2 screws coming up thru the board (one in each corner) I actually took nuts and secured the screws to the board nice and tight first. That way I don't have to worry about taking the board off the tray to tighten the nuts on top of the block. The screws wont move so it's a lot more convienant. I'm thinking of putting 2 more screws in so I can have them in all 4 corners. Just need to get off of my lazy butt and do it.

Thankx... I wanted the springs to save myself from crushing it, and knowing I squished those evil pads down enough to make contact with the CPU...
bTw, I have a spacer, if that helps anything.

I want to make sure i don't crush the CPU core, but I also wanted to know that I squished those evil pads down enough to make contact... I have a spacer if that changes anything...
Maybe I should take the pads off?

four 4lb springs would give you 16lbs four 16lbs springs would give you 64lbs and that seems like a lot of weight to be putting on that little fragile core "the spring's would of course have to be near maximum compression"

you have a shim, then all you need to be sure is that you have semi even force and enough force putting down. As far as the springs pushing down, i am not sure if the just add it up works. I can see how, but it is something I need to think about, although I am not too sure.

As far as using a spacer, Thats what will save you from crushing the core. That's more or less what there designed for. I've never used a shim so I'm not sure about taking the feet off or not. If the shim fits in between the feet I'd just leave them on. There not going to hurt anything.

Takeing the pads off is dependent on the design of the shim. Some shims have circles cut that go up flush with the edge of the pad and some leave some space for compression of the rubber pad. My exsperince is that the type that goes flush with the edge of the pad is a poor design. When the pads compress they have nowhere to go and can impead the contact of the heatsink/waterblock on the core. So taking them off would be good in this case. If the circles cut in the shim leave compression space just leave them on.

its a simple linear equation force one + force2 ect.. = net force and springs are generally rated near max compression

Thankyou All!!!
got enough info...
thanx again!
