LED heatsinks and cooling

These tiny heatsinks measure just 11mm square and 5mm high. They are finished in black anodising for good heat radiation and come with thermal tape already applied, so just peel and stick. These are...

These tiny heatsinks measure 13mm wide, 18mm long and 6mm high. They have a 13mm x 13mm square heatsink surface which has thermal tape already applied. Originally designed for cooling RAM chips in...

These great little heatsinks measure 20mm diameter and 15mm high and have a 12mm diameter solid centre section. They are perfect for adding heatsinking to LEDs of up to a couple of watts, more if you...

These great little heatsinks measure 20mm diameter and 20mm high and have a 5.5mm diameter hole through the centre. They are perfect for adding heatsinking to LEDs of up to a couple of watts, more if...

These are nice little heatsinks that measure 28 x 28mm and 11mm high. They are ideal for cooling power LEDs up to a couple of watts, or more if you use a fan as well. They come complete with thermal...

These tiny fans measure 30mm square x 7mm thick. They are rated at 5VDC, with a rated current of 0.1A (0.5W). Rated speed is 9,000rpm, airflow is 3.62CFM at 5V. Rated noise is 28±10% dBA. Hydraulic...

Nice circular fan-style heatsinks for cooling LEDs up to 3W or so. They measure 36mm diameter by 22mm thick and have a black finish. Centre solid section is around 15mm diameter. Note that it's...

These little fans measure 40mm square x 10mm thick. They are rated at 12VDC, 0.08A (around 1 watt). Rated speed is 5800rpm, airflow is 5.4CFM at 12V and rated noise is 28dB. These are ideal for...

These are nice little heatsinks that measure 40 x 40mm and 10mm high. They are ideal for cooling power LEDs up to a couple of watts, or more if you use a fan as well. They come complete with thermal...

These are auto resetting bi-metal thermal switches which are perfect for protecting power LEDs or turning on a fan when their temperature is exceeded. Mount one of these on the heatsink of your LED...

These are nice little heatsinks that measure 53mm diameter x 20mm thick. They are ideal for cooling power LEDs up to 5 watts, or more if you use a fan as well. They are designed to allow you to...

These tiny heatsinks measure just 8.8mm square and 5mm high. They are finished in black anodising for good heat radiation and come with thermal tape already applied, so just peel and stick. These are...

This non-electrically conductive glue is ideal for bonding power LEDs to heatsinks instead of using screws to hold them down. This is Stars 922 glue. Tube is enough to do up to a dozen or so LEDs....

This is a small quantity of GD66 high quality grey coloured heatsink compound in a plastic softpack, ready for use. Just tear on the cut mark and squeeze out the compound. Ideal for use on ICs, power...

These heatsinks measure 50mm x 25mm x 10mm. They are designed for the LM2596 power modules elsewhere on this site but are also suitable for cooling LEDs of course. One of these will handle around 2-3...

This is ideal for sticking power LEDs to heatsinks or attaching small heatsinks onto LEDs and ICs etc. It comes on a nice long roll of around 10 metres of thermal tape, so should last you a while!...
