Answers to your questions:
- Don't ever add lubricant as doing so will damage the blower unit. To clean the blower, you need to (carefully!) remove the board from the chassis (you have to remove two screws to do so) and then, using a can of compressed air, blow air into the blower inlet from various angles. If it's really dirty, you should see dirty air coming out the other end of the heatsink tunnel.
- No, you cannot add any fans. The blower is predicated by the limited amount of space in the chassis for this.
- This is not a task for the uneducated. There is often a thermal pad, as well as paste, under the heatsink. You need to replace both if present.
To me, it sounds like the blower is working harder because of the ambient temperatures. There may be nothing wrong; it is just going to be louder in such temperature environments.
Yes, it can most certainly power any 2.5" drive on the market, provided that they are thin enough to fit in the drive bay (there are a few large capacity drives on the market that need more power, but these are too thick to fit into the NUC's drive bay). It sounds like this drive of yours was on the verge of failing already.
Hope this helps,
