Re: [GUIDE] Jesse's Official Overclocking (voltmod) Guide For Gridseeds
Thanks for naming the people who where involved in this.
Great appreciation for doing this and helping the community.
There is one proposal which i would want to make:
Instead of using thermal paste use thermal pads, and place them in the way like this:
Black should be the thermal pad. Red is the area which should not be covered by the thermal pad.
Problem with the thermal paste is that the heatsink actually lies on the red parts and if you tighten the screws too much you risk to crack soldering of those parts. ( I had this on 5 units, which i needed to resolder and from now on i stick only with thermal pads.
I'll recommend this one: http://www.amazon.de/Phobya-W%C3%A4rmeleitpad-XT-1x120x20-wei%C3%9F/dp/B0051C287K

What about Copper shrims 15mmx15mm covering each individual chip and applying some good thermal compound paste 5.6wMK?
Awesome, yeh I just noticed they said extra heat dispense stuff is needed, they must do a good job to get 1200mhz with the same results as the lower resistor, I am guessing it will probably be at 530khs - Well you know what I have in the mail, 15mmx15mm square 1mm Copper shrims
And some good thermal past better that that silver stuff...
just wondering though with the shrim how would you recommend placing it on the chips? would you do 5 shrims per device and put thermal paste between the shrim and the chip and also between the shrim and the seed heatsink?
What do you think?

What do you think?
Maybe use 1.5mm instead of 1mm? (I read the height of other components are not allowing a good contact with the heatsink)
What thermal silicone paste are you using or do you even need any with this pad?
You think 1.5mm?? Hmm I saw originally people using 0.5mm pads? so I thought I will do one better and get 1mm just incase, now I see 1.5mm lol Argghh.. you really think 1mm is too small? Also I am using 4g Arctic Cooling MX-2 Thermal Compound Paste---- Thermal Conductivity W/(mK)5.6 Maybe I should also get a bunch off 1.5mm shrims also, they are VERY cheap and cut perfectly into shape and provide the best W/(mK)--- so I thought you cant loose here. Do you think I should apply past to top and bottom off the shrim? And by applying the shrims this means I will not have to tighten down the heatsink as much is this right?
