Some of our users had recently report glue residue on the base of their newly purchased HSF after removal of protective film. We are working with our factory to see if there is a feasible alternative that is readily to adapt. In the mean time, we suggest these steps for customers with glue residue problem to remove these sticky unsightly performance hurdle, and realize the true performance potential of our HSF.

* The glue from the protective film is a thermal insulator, which would keep thermal energy from working CPU right on top of CPU die

For removal of these glue, you need:

Petroleum based solvent or acetone (automotive carburetor cleaner, paint thinner, nail polish remover, etc.)
1 pair of rubber gloves
1 clean soft rag

Please keep away from heat source and always work in a well ventilated area.

For experienced users, a shim is not needed in installing socket A heat sinks. Besides, a shim does accumulate heat around CPU die. Our experience shows a shim may have higher temperature than without a shim for about 2~3°C in normal operation.

Please note: if you must use a shim, be sure to purchase one that is non-conductive.

Different Vendors use slightly different method as well as different thermal
diode locations in gathering data for Thermal resistance calculation. for
instance, Int*l and A*D both has their own Thermal design guides, however
the locations for thermal diode are different. We at Thermalright feel that
it is better for 3rd party to post these numbers/information than we post
our testing results ourselves. You may able to use information from
following websites to get a pretty good feel on how our products will
perform for your configuration.
