If you have ever used traditional heatsink paste for CPU installation, you know how messy it is and how difficult it is to apply an even layer that is essential for proper cooling. StarTech's HSFPHASECM Thermal Pad Heatsink Paste Alternative is the solution. With easy "peel and stick" installation, there is no mess and no fear of uneven application. The StarTech HSFPHASECM Thermal Pad Heatsink Paste Alternative is electrically non-conductive, has low thermal impedence, conforms to surface irregularities, and is solid at room temperature while softening at heatsink operating temperatures. This package includes five applications and is backed by a 1-year limited warranty.
