Cleaning your Desktop PC's Cabinet Fan

After almost 6 years of continuous PC usage I found that my PC cabinet fan had become very noisy. A PC technician told me to do little bit of oiling. I tried cleaning the fan blades superficially & applied some oil near its spindle. Unfortunately that did not work & the fan continued to be very noisy & would sometimes stop rotating. Though it was not a critical component for the PC to run, I still thought that I had a role to play for the fan to function properly (:-)

I then started looking out for options to dismantle the entire unit. Though it seemed difficult at first sight, but very soon I discovered how easy it was to dismantle the fan. I first disconnected the Power Supply running to the fan from the SMPS & brought the chasis outside. The first image on the top shows you the fan blades (one blade broken due to my experiment) & the outer chasis. On one side of the chasis you would find the fan manufacturers advertisement sticker stuck on it, along with the fan rating & other specifications. On carefully removing the sticker, you would find a small Black plastic disc (shown using a red arrow) at the centre. On removing the disc you can now see the fans' spindle held to the inner core & the chasis using a small white stopper (shown using red arrow). On carefully removing the stopper, the fan blades along with the outer core would easily come out from the other side of the chasis (shown in the next diagram).

You can now remove all the dust stuck in the joints & the spindle, clean the fan blades carefully & reinsert the spindly back to the chasis. Now fix the white stopper & apply some oil near the spindle area on both the sides. After the oiling is done cover the spindle area with the black disc & seal it once again using the manufactures sticker or any kind of adhesive tape.

You can now fix the fan back to the PC cabinet & enjoy noise free operation for the next couple of years. Isn't that very simple? Why don't you tryout & share your experience with me.

Configuring your large External USB HDD for your USB-enabled TV/Home Theatre

2 months back I bought a new LG LCD TV (model 32LG80FR also called Jazz Series) to enjoy Movies at home. But the Movies were not limited to the movies broadcast on the Cable Network but few DivX videos which I already had it on my PC. This model was selected as it had USB support, a feature which was also present in my 3 year old LG Music System. The only difference was that my LCD TV USB support included DivX support in addition to MP3 & JPEG ( already supported by my Music System).

Unfortunately my existing External USB Hard Disk (HDD) was running out of space, which I generally use to have my PC backup. My PC's HDD was also running out of space (20 + 40 = 60 GB). Rather than upgrading my PC's Internal HDD I planned to buy a large enough External USB HDD which would handle my Storage requirements for at least the next 6-7 years. I thus went for a 1 TB (1024 GB) Seagate FreeAgent Drive. This drive provided good aesthetics along with good technology. It went on good along with my TV, Set-Top Box & my Music System. It needs to be powered externally & the Power Adaptor has Universal Plugs provided.

I then plugged the FreeAgent Drive to my PC & copied few DivX's & MP3's. When I then plugged the FreeAgent Drive, my LCD TV popped up the message "DEVICE NOT SUPPORTED". I later realized that the FreeAgent Drive was formatted with NTFS File System by default & I was aware that all USB-enabled Systems currently only support FAT16 or FAT32 File Systems.

I thus partitioned the FreeAgent Drive into two partitions - 100 GB for my Music & Movies & 900 GB for my Data Backup. I now had a new problem - Windows Explorer did not allow the 100 GB to be formatted with FAT32 File System. I then googled & found that Windows Explorer would provide option to format a drive in FAT32 File System only upto a maximum of 32 GB else you need to use the Command Prompt & type "FORMAT " /FS=FAT32". I now partitioned the FreeAgent Drive to 32 GB & 968 GB partitions.

And then I copied all my DivX Movies & MP3's to my FreeAgent Drive. When I plugged it to my LCD TV, there was some more surprise waiting in store for me. Out of about 24 GB of DivX & MP3's, the LCD TV showed the entire directory structure but was unable to show all DivX & MP3 files. I then called an LG Technician who said that the LCD TV had USB support upto 8 GB. Since I needed a workaround I began my extensive R&D (which I always do :-). I tried all possible options - right from defragmenting to reducing Folder hierarchy.

After Copying/Deleting/Plugging/Unplugging my FreeAgent Drive numerous times to my PC, I came to the conclusion that the LCD TV worked best with smaller Folder Names & least Folder hierarchy. Though my conclusion might be wrong, I would suggest people using large External USB HDD's with their Systems to use only one level of Folder hierarchy. So just create Folders with the name of the Albums or Movie names under the root drive & copy your DivX & MP3's directly onto them.

I would eagerly wait for comments from people who have tried something different.
