Default Modding Gigabyte 1155 Board with Mosfetheatsinks?

Hello,
a few days ago my Asrock 1155 Mainboard broke, somehoe i managed to damage the bios. As i didnt want to give up my 2700k so fast, i bought a new board over ebay, the prices are high and theres not too much choice, because the 1155 boards are still popular, but not produced anymore.

So i got a good offer for a Gigabyte Z68 AP- D3, which looks almost new, a nice little, simple board which should be ok. Im usually never running more than 4,4 ghz anyway on all cores.

What i didnt like too much: My old board hat complete Heatsinks over all mosfets from all 8 phases. Pretty stupid D-Pak-Mosfets, but they were all cooled. The new board has got 1 pretty nice heatsink, but it seems to cover only 50% of the mosfets. The mosfets that are right over the cpu, are "naked"..

im planing to go maybe 1,3-1,35 Volt on a long term and was wondering if it makes sense to cover the uncooled mosfets, i got stuff here, some Pads and heatsinks left from my morpheus GPU-Cooler, so i could manage something.

Thing is i really dont wanna take a risk, like shortening something. Is is ok to put 1 stripe of pad on the mosfets and put a aluminum or copper heatsink on it? Or must all mosfets have a single small pad and heatsink, so there is no way the can make contact? Would contact be bad anyway?

So why did gigabyte use only 1 heatsink anyway, maybe it has something to do with up-and downside mosfets and the ony that are under the heatsink get hotter?

There is no much point in the heatsinking plastic MOSFET packages in this particular case.

As far there is bit of airflow from CPU fan - you will be fine as is, without any mods

Try other slot? Check if any CPU skt pins bent?
Wipe GFX PCIe slot connector pads with pensil eraser just in case.
