I would like to know if anyone has had success using an alternative substance for thermal paste. (I heard wheel bearing grease was good)

I do appreciate the warnings, but I am not worried about the hardware and it will be fun to test.

    It's not like thermal paste is expensive or hard to find... – Shinrai Jun 03 '11 at 16:52
  • No kidding Shinrai. – KCotreau Jun 03 '11 at 16:54
  • I know this is a dupe I just have to find it... – Supercereal Jun 03 '11 at 16:54

    Okay so not and exact dupe but close enough... http://superuser.com/questions/102145/is-it-ok-to-use-toothpaste-instead-of-thermal-paste-when-fitting-a-cpu – Supercereal Jun 03 '11 at 16:55
  • if you're not worried about the hardware and think it will be fun then why not just test it? – Xantec Jun 03 '11 at 16:58

    @Xantec - That's what I will have to do. I thought I could get some knowledgeable insight here. – Aducci Jun 03 '11 at 17:02
  • What's with all the closevotes here and none on the toothpaste question? I mean, the toothpaste question is just asking for one specific thing while this one is much more general in scope. – AndrejaKo Jun 03 '11 at 17:17

    @AndrejaKo; That is a specific query with a reasonable answer. This is a general question with no one answer, and no good answers other than "Just use thermal paste". – Phoshi Jun 03 '11 at 18:47

    Agreed with @Phoshi. Also, here's a dupe anyway: [Alternative to thermal grease](http://superuser.com/questions/279937/alternative-to-thermal-grease) – slhck Jun 03 '11 at 19:04

I wouldn't recommend anything but thermal paste, you need something non conductive. And just to be on the safe side I would use Thermal Paste.

I currently have used Arctic Cooling MX-2 and Arctic Silver 5.

  • I assume you mean electrically "non conductive". The whole point is that it is conductive...for heat. Silver-based thermal pastes will conduct electricity to some degree, so it is important that they not accidentally come in contact with electrical components. – KCotreau Jun 03 '11 at 16:58
  • Arctic Silver 5 claims that isn't conductive, but is it slightly capacitative, so you still have to be careful with it. – Shinrai Jun 03 '11 at 19:39

I don't know where you heard that. Grease is to reduce friction, which may cause less heat to be created, but there is no significate friction where the processor meets the fan so there is none being created that way anyway. It is not designed to dissipate heat.

BUY THERMAL PASTE.

You'll usually get better than nothing performance for every greasy thing you can place and some people say that water works fine too. The main problem is that most of the unusual greases will evaporate over time and behave badly when they dry. So if you really need something which is not thermal paste, get some grease designed for high temperature operation which will not dry out quickly. Oh and it needs to be stable enough not to corrode CPU heatspreader or heatsink.

And don't forget to use thin layer! There needs to be just enough to cover the processor and heatsink surface.

JB Weld works very well, but is permanent.

  • Really? Any source? I'm not doubting you, this notion just fascinates me...JB Weld is pretty hardcore for this sort of thing. – Shinrai Jun 03 '11 at 19:40
  • It was back in the late 90's I read an internet article on using different unorthodox materials as substitutes for thermal paste, at the time JB weld worked as well or better than the best pastes of that era, no I never saved the link or page, wish I did. I still use the old white silicone based thermal paste on older processors, works great and is inexpensive and still easy to find, just did my old Dell D600 with a 1.8 ghz mobile processor, runs as cool as it did before the remount of the heatsink. – Moab Jun 03 '11 at 19:58
