RE: Dell t3500:Small alum. heatsink next the CPU heatsink missing
Yes this is the part number for the heatsink., It will not however be available anywhere because the board does not operate properly without this part. T021F Dell Passive Heatsink for Precision T7500 is another number.
The entire system is less than what people ask for Just the motherboard.
Thats not paste its a silicone PAD. Typical for this type of Heatsink.
Doesnt need to be cleaned or replaced.
