Dear Valued Customer,

We are contacting you today to notify you of a New Revision of the HS-53x50x13 Heat Sink, an option on the TS-7970 from Technologic Systems.  The new heat sink device is a complete form, fit, and function drop in replacement for the old device.

The affected products are: TS-7970

Technologic Systems' supplier for the HS-53x50x13 has revised this heat sink device, which has resulted in minor mechanical changes which may be noticed by current users of the device.  The new heat sink device has the same thermal performance as the previous device.  It is the same height as the previous device, however you may observe that there are now slots in the fins, and the flat base of the part will be a little more narrow.

Due to the growing popularity of the HS-53x50x13 Heat Sink, and the short notice provided by our supplier we will be making this transition effective today.  Please contact us if you have any concerns and we will do our best to smooth this transition for you.

Technologic Systems appreciates your business. If you have further questions or concerns, please contact us by either replying to this email or filling out the contact us form at

Best Regards,
