I have removed heatpipe assembly as I am going to water cooling, and have a question
I have replaced the OEM heat pipe assembly on my motherboard with a Enzotech Sapphire SLI water cooled NB block and an Enzotech SLF-1 solid copper SB heatsink with fan. I have also modified a Thermalright HR-09 U MOSFET Cooler to mount over where the factory had an aluminum block (I believe this is the PWM area). I cut out the thermal tape as per Praz's suggestion in another post, and then used Arctic Cooling MX-2 thermal paste on the raised components, before mounting the MOSFET cooler to the motherboard through the OEM holes in motherboard.
Also note, those two long chips that were inset on the MB from the aluminum block are being cooled with Swiftech MC 14 copper ram sinks, so that should help. Also, I have two 120 mm Yate Loon Fans directing cool air in from the top of my case (across MOSFET cooler, CPU and NB water blocks, and memory slots), and a 120 mm Scythe SFlex SFF21E fan exhausting air just above where the MOSFET cooler and exposed resistors are located.
I believe this setup will cool very well, but there were a couple small items that were under the OEM aluminum block that are no longer covered. I believe they are resistors, but am not certain. My question is this, do I need a heat sink over the couple of resistors which are now open to the air (used to be covered by the aluminum block on top left corner of MB), or will my current air cooling suffice?
