  • Thermal Paste Advice

    Hi All,

    I've got a CPU arriving this week and intend to cool it using a Zalman CNPS10X Performa. Supplied with the heatsink was a small pouch containing an amount of ZM-STG2M thermal paste, but I have some Arctic MX-4 left over from when I replaced the thermal pad on my laptop a couple of weeks ago. Which is the better performing of the two, or is the difference small enough that I should just use the MX-4 since it's already open? The MX-4 has done a superb job on my laptop (running an i5-2410M), keeping temps below 70degC where they previously would've reached over 90.

    I've also got some ArctiClean Remover and Surface Cleaner: http://www.aria.co.uk/Products/Compo...roductId=40436

    Is it worth using bottle 2 on the CPU and heatsink to "purify" the surface before I mount the cooling gear, or is this more for when you've cleaned old gunk off?

    Cheers!

    I would use MX-4, Zalman usually make good stuff so you could always try it first.

      I have a very similar HSF myself and it's a cracker...but It was 2nd hand so I didn't get to use any Zalman paste - I'd also be tempted to go with the MX-4 and save the unopened Zalman paste for an emergency.
      As for the thermal interface purifier stuff I use about 2/3 less of that than bottle 1 (meaning I end up with a massive stockpile of the second bottle after the 1st one is depleted) but sometimes it's quite remarkable what it can lift from what you thought was a spotlessly clean heat sink - it won't hurt to give the two surfaces a quick rub with it.

        MX-4 it is I think, the syringe applicator will probably make for a neater time than I would have with the Zalman pouch anyway

        Snap, bottle 1 of my ArctiClean is almost empty after I used heaps of the stuff trying to get a 5 year old thermal pad off my laptop heatsink, it did a very good job though!

          It's always good to remove it using the cleaner, as heat transferrance goes down to as small as atom level for efficiency.
