Pre-Owned (Delidded) Intel i7 4790k 4.0GHz CPU, like new working condition in original retail box with never-used stock heatsink/fan.

I personally delidded this CPU with a Rockit Cool Delid/Relid Tool. Used Thermal Grizzly Conductonaut Liquid Metal as new TIM, and resealed CPU with Permatex High Temp Gasket Maker. Operation was successful, as expected, resulting in very cool temps. This classic, highly over-clockable Intel Core i7-4790k 4th Gen (Haswell) CPU features 4 Cores, 8 threads, a base clock of 4.0GHz and can turbo up to 4.4GHz. It has an L3 cache size of 8MB, a TDP of only 88W and requires the socket LGA 1150 (Z87 or Z97 Chipsets). On-board graphics are provided by Intel HD 4600, and new stock heatsink and fan are included.
