Ok ill set the scene, 2 1U servers made by.. well who cares, bought from a well known auction site bare bones, gradually getting the kit together for them, get CPUs get the 1U height OEM copper heatsinks. now.. theres no clips.. rather than paying the extortionate costs from the OEM for them do you reckon some well placed cable ties will be enough to hold the heatsink down (there will be only the weight of it really no real force on the CPU the ties will just stop it hopping off when the box is moved really) and will they take the heat from the immense P4 2.8s? lol
Cheers for any input, i could just risk it as we know that the P4s can throttle back from high temps but id rather not have to scrape out molten cable ties
yes i know.. call me john wayne (cowboy)
I suspect cable ties wont stand up to the heat, they arent intended for anything like that use. If there is nothing that can easily be shorted out then try copper wire instead. loop it through and twist the ends together. This my not create enough pressure though
the problem is the usual clips would be spring and attach to 4 posts that come up through the heatsink, i think im doomed to pay stupid money for silly little clips :(
The resin will dry out and theyll fail just when you forgot about how cheap a bastard you were. :lol:
gah i dunno will think about it after iv got a price, they are only some old dell powervault 745s anyway
i folded and ordered the clips, Ã,£70.50 for 2x heatsink clip kits :(

!!!
Insanitos!
Did they bend you over and do the business as well?! Oy, Id imagine a couple clip kits shouldnt cost more than 30 pounds, and even thats highway robbery!
Im getting into the clip kit business. Seems that the profit margin is something like 10K%
/faint
ah well they dont sell a lot of them but when you need a set your stuck so can bend you over a bit... bastids lol
I would probably have tried thermal glue TBH. Thats cheaper, and if you buy the decent stuff it doesnt degrade for 5 or 6 years.
cable ties would have worked gread !!!
youve no idea how many cable ties I use just to hold my world together !
Id have cable tied it tight. The plastic clips just hold it on, doesnt actually really squeeze it down.
cable ties, upon cable ties just incase they give.
cable ties dont dry out, they are made out of a polyproulene which only degrades after a couple of years of heat/cold exposure.
Thinking about it a pentium 4 can be quite expensive :) though it does have thermal protection, so Id definately just cable tie it.
If I was really worried Id thermal epoxy it, and cable tie it.
Id have just used a thermal epoxy to stick the heatsink to the chips tbh
Never thought about epoxy...Id return the clips as soon as you got them. :lol: Ã,£70 buys a lot of pints and kebab. :P
Im still a thumbs down on zippies for such an app. I used them on my bike to attach fenders on the front fork, and they needed replacement about every 6 months as theyd get hard and crack. Probably UV exposure, but heat can do the same.
Reminds me of when I decided to stay after work one day and clean the starter motor on my car, it would stick once or twice a week.
After cleaning it I managed to drop it on the floor, and the solenoid top with the electrical connections broke off :(
Not being able to get a replacement I decided to repair it with cable ties, thinking it would only have to work for 2 days till I could get another.
It would have to take a good thump when the solenoid kicked in, and would have to make a good electrical connection.
That was 4 years ago and its still going strong :D
LOL cable ties rock! well as iv ordered them ill use em but i can always consider ties and resin next time i have the same problem

heat and uv are the main causes of degradation, thats how come they add urea to pvc windows because they go yellow and crack.
Cable ties woulda been absolutely fine, I once held down a home made copper heatsink thing with just some string (duron700@1ghz iirc).

lol thats crazy
LOL
Thermal epoxy and cable ties FTW!!! :D

The nylon the string is made of can withstand much higher temps than polypropylene cable ties though
I remember getting a load of cable ties from Maplin back in the day, apparently gaurenteed to quite a high temp.
Kanthal wire is always good, just what you need when your exhaust falls off and you want some really thin, stiff, cheap and mega heat resisting form of support.

Might be making some of them out of nylon now, best check if anyone buys any for high temp work.

I just used a bit of copper wire, soft enough to bend into shape, and twist the ends together, heat resistant and strong enough to hold an exhaust in place.
Most seem to use a rubber ring now.
should have used some thermal epoxy. I belive artic silver company sell a type that glues themselves to chips.
