My new haswell build finally upgraded from q9550. I chose a 4650K in the end and a gigabyte Z87-UD3H with 8GB of Kingston HyperX Genesis Grey DDR3 PC3-15000C11 1866MHz

VID is 0.8250v

So after building my temps at idle were between 30-33C on all cores.

I then overclocked to 4.6Ghz to see if it would be stable at stock voltage and it is, but its a bit hot when running Prime64, cores are now around 83-89C

So I delidded using the Vice method worked a treat. I have then put Prolima Tech PK-3 between them all a thin layer.

After starting up and running prime again I am still getting 83-88C

So what thermal compound should I use between the die and the cover as I think the PK-3 is the problem. Or is 4.6Ghz just to fast for a Haswell.

Will try and post the photos of it all later

Advice welcome.

Happy the de-lidding was successful
 
If it was Ivy would recommend Coolaboratory Liquid Pro or Ultra.

Wouldn't recommend it for Haswell though as it's electrically conductive and if you got it on the components just to the side of the chip die it would probably kill your chip (afaik).

Hopefully someone that has a de-lidded Haswell themselves can be of more help.
 
oooo well done sir!!!

+1 for the liquid pro,and yeah keep it away from the run of resistors alongside the die and you'll be ok,it doesn't run

you only need the smallest amount of liquid pro,pastes won't lower temps at all over what intel stick on there originally,been there done that

its your paste that's the issue,you need liquid pro
 
I would go liquid pro. There is a few ways to protect from the electrical conductivity of it if you are not confident. Some people say nail varnish over what you want to protect, though to me i would trust it. I personally would use a thick layer of non electrically conductive viscous TIM over what you want to protect and liquid pro on the die. Liquid pro shouldn't run but if it does, it certainly wouldn't get through the non conductive TIM.

Click to expand...

Do thermal adhesive-type products dry hard? It could be useful for creating a solid protective 'dome' around that stack of resistors.
 
**** 4.6 on stock voltage that is 5ghz material there on water +liquid pro or ultra...
 
It was easy to do as long as you lock the heat-sink tightly in the vice and then gently hit the board with a piece of wood\hammer. It came off really gently not suddenly I was really surprised. I did have a beer after I put it in the motherboard and it worked though. Could have been an expensive £180

I am running a Cooler Master V8 and have nowdropped cpu voltage to 1.188V and at 4.5Ghz cores are 68-70C which is ok max I like really. Prime 64 has been ok for an hour

I think the liquid pro is in order. then maybe water cooling but that involves new case.

I don't think you'll need watercooling tbh,I saw a good 20c drop on ivy,maybe less on haswell Idk,but atleast 10-15c

Just be carefull with the transistors next to the die and you should be fine
 
The plan is to nail varnish the resistors although they are 5mm away from the die and then liquid pro the lid back on.

I think haswell just generates a lot of heat. If goes from under locked and 25C at idle to 100c within seconds. Let's hope is not the future.
 
When you say stock voltage, do you mean that you checked the load voltage at stock speeds, noted it down and then fixed the voltage at that level/applied a negative offset to achieve the noted voltage at 4.6 GHz OR do you mean that you simply left the voltage settings alone (auto) and raised the multi to 46?

I think it is probably the second of those options, in which case it will be using far more than 'stock' voltage as auto voltage tends to use excessive voltage for the frequency. It would also explain the temps being so high- Haswell runs hot, but if it was genuinely using only stock voltage at 4.6 GHz, I doubt they would be that hot.

Try applying varying levels of negative offset until you reach the stability point.
