Tuniq TX-2 Thermal Paste



All modern PC CPUs produce enough heat that they need a heat sink. Almost all of them need a heat sink with a fan. Many heat sinks come with some sort of thermal transfer paste pre-applied - typically a patch of grease; thermal paste; goop or whatever you want to call it.

With the heat output of modern CPU's, and even more imortantly, overclocked CPU's, there just has to be something between CPU and heat sink. The reason why there has to be something there is that the two mating surfaces of processor and sink aren't flat. They may look flat...They may have a mirror polish. But, on a microscopic scale, they are vastly different.

Without thermal transfer compound, everywhere heat sink metal doesn't mate with CPU package material is a teeny-tiny air gap. Air is a good thermal insulator. As long as your heat sink looks flat when you lay a ruler on it then there'll be a decent amount of actual contact, of course, but the amount of heat that'll actually make it around the air gaps may be surprisingly small. Hence, thermal compound. It's grease with lots of minuscule thermally conductive particles mixed into it, basically. It doesn't conduct heat as well as direct contact, but it's a heck of a lot better than air gaps.

Now here is where the picture becomes a little grey, and perhaps a little confusing for the uninitiated. Not all thermal pastes are created equal! Many people tend to purchase a thermal paste that the majority says is better, quite often without considering viable alternatives that exist out there. It's understandable, it is the nature of the consumer. Take Arctic Silver and their AS5 thermal paste for example. Sure it's a proven performer, but there are better performing pastes out there, and quite often cheaper than AS5. One of those pastes is sitting beside me right now.

Today I have been given the opportunity to test Tuniq's new TX-2 thermal paste which has been stated as achieving the best interface between the CPU and heatsink because of its uniquely designed molecular size and shape. For those of you who don't know who Tuniq are, they are a subsiduary of Sunbeamtech, and specialise in case modding hardware. Here's what they have to say about themselves:

Tuniq TX-2

According to Tuniq, their TX-2 thermal paste is neither metal nor electrically conductive and is the most effective thermal compound for your CPU's and coolers. So I guess we're just going to have to test it out!

Let's have a look at the specifications of Tuniq's TX-2 thermal paste...


The specifications for Tuniq's TX-2 thermal paste were taken directly, and unashamedly from the product web page .

Appearance  Grey
 Viscosity  285000 cP
 Thermal conductivity  4.5W/mK
 Operating temperature  -45°C ~ 200°C
 Specific Gravity  3.96 @ 25°C
 Volume  3.5g

With an operating temperature of -45 deg C through to 200 deg C, TX-2 could possibly be used as an alternative to Arctic Silver's Ceramique. Further, with a viscosity index of 285000 cP (centi-Poise) it falls somewhere between warm peanut butter and commercial grade toner ink. Mmmm easily spreadable...


Whilst there isn't a heck of a lot of information on Tuniq's website regarding TX-2 thermal paste, it does include some impressive features. It will certainly be intersting to see how the Tuniq TX-2 stacks up against Arctic Silver 5.

* Low thermal resistance for superior heat transfer, 4.5W/mK
* Small molecular size makes a better contact between the heatsink and heatsource.
* Thin bond line for hi-efficiency conductivity
* Low bleed under high pressure
* Spreads easy - clean consistency
* Help the low-pressure clip design of cooler to achieve better cooling performance.
* RoHS compliant
* Not Electrically conductive

Let's head over the page and have a look at the TX-2's packaging.

A poor attempt at that.

Me either, but i an't sorry about it.

If AMD want to sell them then they need to cut the price by £70-100. Not stick a differeent hs on.Quote
