    Hey,

    Need some advice from you knowledgeable folk on thermal grease as I guess this is some of you know a lot about this topic!

    I'm creating a heat sink with multiple heat pipes running into it. It is made of 5 aluminium blocks each 10mm x 250mm x 50mm bolted together. The heat pipes come in at a right angle then run between each block.

    I want to ensure as good a contact between pipes, aluminium and the case. To do this I am looking for some thermal grease but don't want to buy a fortune of little syringes of CPU paste.

    To this end I am after:
    • Thermal paste that wont set
    • Good thermal conductivity
    • Cheap and easily available
    • Works with Aluminium and Copper
    • Wont give me cancer or some form of poisoning
    • I'm not worried about electrical conductivity as this is just for the heat sink
    My research leads me to try to find something with a Thermal Conductivity over 5W/m K.

    Im leaning towards this: https://uk.rs-online.com/web/p/thermal-grease/7074736/

    Anyone got any other ideas? (Memes are acceptable too)

    MX-4 is my go-to Tim. Have you considered using copper instead of aluminium so you can solder the heatpipes to the rest of the block?

    I was going to suggest GELID Solutions TC-GC-03 as it comes in a pot, but it is only 10g and $30 USD (£23.98 from Amazon.co.uk).

    Will go with the MX4.

    I would liked to have made the sink out of copper but it would have blown my budget

    Blimey, even on eBay you're looking at £80.

    What's the heatsink for? Are the heatpipes having direct contact with the heat source? Might be worth seeing if you can find a full teardown of an Asus direct cu cooler, see how that's constructed.

    Its for my build here, its to try to transfer the heat from a 1070. Just finished hacking the Aluminium up to make it.

    Amazon are delivering 20g of MX4 tomorrow for just under £14. Since I brought it its gone from £13.94 to £17.99 so that was nice!
