i had to remove my msi motherboard's northridge heatsink cause it was too big and in the way of my rad fans . so my question is if the killer ethernet controller on the mobo is malfunctioning is it because of no heatsink ? or is it something else ? cause it only happens when i'm kicked out of a call of duty game , otherwise my computer fucntions as it should ?!
