PCI Slot Case Fan - Keep that CPU COOL! New!

High Air Flow - High Static Pressure Fan. Cooler computers last longer! This fans work is exhausting. Keep that overclocked overstuffed Mac or PC cool! Electronic components operate their best at lower temperatures and last longer. Here is a low cost way to add life to your system. These are great for Mirror Door systems since they help exhaust that extra heat from the top of the machine (place it in the uppermost slot). They are also good insurance for your high powered graphics card since when position right next to them they help keep them cooler. On other systems I would reverse the flow to draw cool are in from the bottom most PCI slot (swap the wires). 3 x 3-inch (90 mm) blower fan, 2500 RPM fan speed and an air flow of 6.92 CFM. Fits in any open PCI slot and uses your hard drive or CD power supply plug with its own pass thru plug. Our $14.77 includes shipping!

60MM x 25MM Replacement Fan

If you have a Digital Audio or QuickSilver G4 you have a small fan in a rubber boot that blows directly on the processor. These fans get dirty and the bushings wear out.

They supply a bit more air and are not thermally controlled which means they are full on anytime your system is powered up insuring your processor runs cooler.

White Thermal Grease Compound - New!

I use a small amount of this thermal grease to keep the CPU's from sticking to the gasket and to improve heat transfer. Use this or any compound sparingly as too much can cause problems. This is also required when you dissassemble Flat Screen iMacs for battery replacement. You actually break the thermal seal on the Flat Screen iMac when you remove the base and it must be renewed when reassembling the iMac to prevent damage. Computer processors generate a lot of heat. Too much heat will cause damage to this costly component! Increase the heat dissipation of CPUs and improve performance with this Thermal Grease compound! Mirror Drive Door owners take note you need to add this to your system now! Tiny syringe type applicator for easy spreading. 1.0 gram of Thermal Compound (Thermal Grease) for CPU use. Covers approximately 10-15 small CPUs. Helps the heat dissipation from a CPU to a heatsink. Our price $2.99 with any order.
