Thermal Paste & Pads in Lebanon.

Paste, pads, putty or phase change?

Thermal paste

Paste fills the microscopic gaps between the processor and the cooler. Thermal Grizzly Aeronaut, Arctic MX-4 and MX-6, Thermalright TF7 and M1, and Cooler Master CryoFuze 7 are all here; Aeronaut, MX-6 and TF7 are listed by their makers as not electrically conductive, so a small spill will not short anything. Choose a 1 to 4 g tube for one or two builds, and an 8 g or larger tube if you build or repaste often.

Thermal pads

Pads bridge larger gaps, such as between a graphics card's memory chips and its cooler, or an M.2 SSD and its heatsink. Thickness matters: match the original pad, for example 0.5 mm, 1 mm or 3 mm. Thermal Grizzly Minus Pad Basic, Advance and High Compression, and Cooler Master Thermal Pad Pro, come in sheets you cut to size.

Thermal putty

Thermal Grizzly Putty Basic and Advance shape themselves to uneven gaps, which makes them a flexible alternative to pads on graphics cards with mixed heights.

Phase-change sheet

The Thermalright Heilos sheet is a solid interface that softens when it warms up, with no paste to spread.

How to apply thermal paste

• Clean off old paste with isopropyl alcohol and a lint-free cloth.
• Apply a small dot or a thin line in the middle of the processor.
• Mount the cooler with even pressure; it spreads the paste for you.
• Don't add more paste than you need; a thin, even layer works best.

When to replace it

Replace paste whenever you remove the cooler, when temperatures climb on an older PC, or when you move a cooler to a new processor. New coolers usually come with paste pre-applied or in the box, so you only need a tube for remounts and upgrades.

Which size of tube?

A 1 g tube covers one or two applications. 4 g, as with the Arctic MX-6, Thermalright TF7 and Cooler Master CryoFuze 7, suits a few builds. 6.5 g, 7.8 g and 8 g tubes, and the 26 g Aeronaut, are for builders and repair benches.
