Fan Blade Interference with Housing and Thermal Issue Solved

I think this should be separated from the thread on "S10 fan runs too fast, too often, too loud."

 

The fan on my S10 has been unusually / annoyingly loud with grinding noises. It's much louder than the typically loud fan on laptops. Thanks, Mark_Lenovo, for insisting that Fan Blade Interference with the Housing can really be an issue. Too bad receiving services from the contracted / outsourced local Lenovo service center is too complicated, ineffective, and consumes too much of my time. I choose the DIY approach and totally understand that my warranty could be voided. I just cannot tolerate the annoyance from the fan anymore. Local service center said they don't have a replacement fan in stock. I would have to wait for a "few weeks" for them to order from abroad (perhaps, Singapore) and would need to call back and check if they have ones in stock or have used up already. I can also queue up by leaving my only computer (yes, this S10) with them during this wait period. 

 

I finally opened the S10 last night with the help of the Hardware Maintenance Manual and did the following:

Fan Upgrade

 

- Disassembled the fan,
- Cleaned it with WD40-like oil,
- Fully filled it with white lithium grease,

- Fixed the blade interference issue by "heightening" the housing with 3 pieces of 0.5-mm thick plastic sheets, and

- Sealed the space introduced by the plastice sheet with UHU Plastic Repair Adhesive.

 

I really saw traces of the fan interference: there are a lot of scratches at the inner surface of the fan housing.


 

Thermal Grease Upgrade

 

Replaced the cheap "insulation" pads between the (1) Intel 945 northbridge chipset + (2) ATOM CPU and the heat sink with Arctic MX2 thermal grease.

 

Soft and Quiet Mouse Click Mod

 
As suggested in http://www.s10lenovo.com/viewtopic.php?f=11&t=577&start=10#p11188 

 

 

P.S. The technician at the local service center did the fan and thermal grease things once for me but it was not thorough and neat. I don't think he understood what he was doing when I saw it last night.

Thanks much everyone who provided me with all the required information!
