Thermal Grizzly Kryosheet
A permanent, reusable graphite pad with nothing to degrade, ranked second at a small thermal cost and a careful-installation requirement.
Backed by one cited source so far - limited coverage
See the source3 of 7 research runs entered this as a product to avoid rather than a pick.
A premium graphite pad that measures up to 3 degrees worse than budget MX-4, so buyers pay extra to lose performance; paste-versus-graphene testing reaches the same conclusion that pads give up real temperature for convenience.

Pros & cons
- ✓ Graphite pad with nothing to dry out, pump out, or replace, ever
- ✓ Community testing reports it can run up to roughly 3 degrees better than MX-4

- ✓ Set-and-forget convenience of a pad
- ✓ A graphite sheet that physically cannot dry out, pump out, or cure
- ✗ Electrically conductive graphite must not overhang the die, requiring careful installation
- ✗ Measures up to 3 degrees worse than MX-4
- ✗ Costs a premium while losing performance versus cheap paste
- ✗ Gives up a degree or two of peak performance
- ✗ Demands careful handling
