8700k hight at stock and delided (without any glue)

MaratM
 Share

I have a dellided 8700k. The IHS is held by socket without any glue. At the moment i’m about to start to watercool my rig with EK z370l waterblock, but because there is no glue under the IHS I’m afraid it will not make proper contact with the monoblock. Can anybody measure the hight of the stock 8700k so i can figure out how much the monoblock’s standoffs have to be sanded down in order to make proper contact with the cpu.

3.2 - 3.4 mm? not very accurate unfortunately based on 2 users.

Hight measurment of IHS is not a problem04-1030x171.jpg.7cf313212ae967883381184c2796a5ac.jpg

the problem is the hight of the stock CPU (with glue and stock tooth paste)

The thickness of the silicone glue that holds the IHS in place is not even a tenth of a millimeter thick.

When the IHS is glued on there is pressure applied to it and that makes the glue layer extremely thin.

As long as you applied enough thermal paste between the CPU die and the IHS then there will be no issue.

Well, based on how much silicon there is, it would be significantly less than 1 mm.

Well, you can measure the thickness of a stock IHS. Alternatively, you can just do plug everything in, cause the difference is probably negligible.

A delided CPU is slightly thinner than a stock one. Even if that difference is miniscule, it's enough to reduce the pressure on the CPU from the monoblock to the point, where someone decided to make a product to mitigate that and you can get it here

In that case, you can email or tweet at der8auer, I'm pretty sure he has the measurements or can easily take them with the necessary accuracy. He's engineering all kinds of stuff for custom cooling, so he is propably the best guy to go to. And if you shorten the standoffs for the monoblock, don't forget to get some thinner thermal pads for the VRM. Since you can get them in 0.1mm steps, you'll be able to get suitable ones.

The thermal pads are not an issue, they are flexible enough to compensate .2 or .1 mm. Looks like i have to sand an measure a few times

It should be fine. You have to understand that even stock cpu's vary slightly in height. So unless you have delidded your chip AND lapped the hell out of your IHS chances are there will be no problem.

I hope I have it figured out

the total hight of the CPU is 4.4mm

according to der8aur pcb hight is .87mm

and according to the reddit thread posted above the hight of the stock IHS is 3.4mm

thus the thickness if silicone is .13mm

all i need is a digital calipers to do get the job done.

thanks to everyone

Update

I was in a local computer shop today, with a digital calipers, measured the hight of stock 1151v2 CPU (celeron) it is 4.39 mm so 4.4mm I found on the internet is correct. have to sand down the standoffs around 0.15 mm will mesure stock IHS hight later.

So the mono block is made for the perfect height of the ihs? So it uses no spring tension I assume. No washers between it and the board either?

It looks like it. No springs, just some nylon washers to put on the back side of the board, exacltly the same as gpu full cover block
