ESGN Nanotherm Silver Thermal Paste & Nanotherm Silver XTC Paste Review



It has been ten months since ESGN has came out with their Nanotherm ICE & Blue thermal paste and I'm still using what I have left of it! Back in January of 2002 I did a thermal paste shootout between the Nanotherm, Arctic Silver 2, and Arctic Silver 3. The Nanotherm paste didn't beat the Arctic Silver 3 paste but it did beat the Arctic Silver 2 paste. Since then, Arctic Silver has came out with a new breed of thermal paste called Arctic Alumina. Today, I will be doing a comparison between the following thermal pastes: Nanotherm Silver, Nanotherm Ice, Arctic Alumina, and Radio Shack paste.

-> UPDATE <- 10/18/2002

Fifteen days have past since reviewing ESGN's new NanoTherm Silver thermal paste product. So why am I here with an update? Well, I got an email from the CEO of ESGN, and he told me that his company revised their new Nanotherm Silver paste and he also said that the new stuff dropped their CPU temps considerably. This new paste ESGN has created is so good that they are calling it Nanotherm Silver Xtreme Temperature Compound or XTC for short. Here are some features and specs of this new formula:

  • Contains a unique combination of custom engineered Silver particles.
  • Contains a synergistic blend of Boron Nitride and "Nano" powders used in our Ice II and Blue II compounds.
  • Total density of silver particles is greater than 82% Silver by weight.
  • Suspension fluid is a high temperature synthetic material designed for continuous operating temperatures in excess of 500'F.
  • Compound is non-electrically conductive (as far as our initial testing indicates).
  • Production syringes will contain a minimum volume of 1 ml of thermal compound (actual volume to be determined).
  • Net weight of the compound will probably be greater than 3 grams (actual weight to be determined).
  • Retail price will be competitive with other high performance silver-based compounds (retail price to be determined).

    Now, the only real way to test this new thermal paste is to put it up against four other pastes (more to come). Skip on down to the "Testing" and the graphs.

    Installation & Closer Look

    I'm not going to show you step by step on how to apply thermal paste, because it's a no brainer. If you don't know, check out past heatsink reviews and see how it is done.

    Here is our test subjects

  • From the top to the bottom we have: NanoTherm Silver, NanoTherm Ice/Blue, Arctic Alumina, and Radio Shack paste.

    Testing system:

  • Abit KR7A-133R motherboard
  • Geforce 2 MX video
  • 512MB PC2100 RAM
  • Windows XP
  • DangerDen Water Cooling System

    Testing procedure:

    I allowed the system to idle in windows for 15 mins after a cold boot, to get the idle temperature. I then ran CPUBurn for a total of 40mins to get the load results. I also shutdown the system and allowed it to cool for 15mins before running the next test. The ambient temperature was 23.5�c +/-

  • Not a very big difference between the NanoTherm Silver & Arctic Alumina in this test. However, the degree lower on idle is nice. This test shows a major improvement over the old NanoTherm Ice/Blue.

    Every time I tried to run the CPUBurn test with the Radio Shack paste, windows would blue screen and crash. I guess the temps just got way too hot and the CPU couldn't hold out. With this overclocking test (1800+ @ 1875Mhz) you can clearly see performance difference between NanoTherm Silver and the rest of the pastes. ESGN has really tweaked their paste since making the NanoTherm Ice/Blue and it shows with the 5 degree difference in this test.

    To many, a few degrees may not seem like much but to me it means a lot. A few degrees may allow you to overclock your CPU a little more or it may even make your CPU last a little longer by keeping it cooler. I have to admit that NanoTherm Silver is very easy to clean up versus Arctic Alumina and especially AS2 & AS3. This is one major plus for NanoTherm Silver. NanoTherm Silver is also very easy to apply, due to the "wet like" texture. The sample that I received is just a preproduction sample and the syringe was hand filled with thermal paste. You will also notice no pretty sticker on it either. However rest assure when Nanotherm Silver hits store shelves it will have a sticker and will be machined filled. Scott at ESGN told me that the NanoTherm Silver syringe & sticker will look similar to the NanoTherm 2 product. I don't know what the MSRP of NanoTherm Silver will be yet, but I think it will be very competitive with the Arctic Silver 3 and Arctic Alumina. I really recommend you check out this thermal paste and try it out for yourself and do your own comparison as I'm sure you will find similar results.

    The new Nanotherm Silver XTC shows some very impressive scores in our testing. It's clear to me that NT Silver XTC will be owning the thermal paste market once again. Now, I'm sure you're all wondering where you can get some NT Silver XTC? Well, I did my homework and contacted ESGN and asked them just that. They said and I quote "Nanotherm Silver XTC will be available around the 1st week of November. The retail price will be equivalent to a 3 gram tube of AS3, although we haven't set the MSRP just yet. Syringes of Nanotherm Silver XTC will probably weigh about 4 grams." Just remember, the release time (first week in November) isn't written in stone, so if that time does come around and you can't find NT Silver XTC anywhere don't sweat, it will come :)

    Again, I'd like to thank ESGN.com for providing us this new paste to review!
