Shin Etsu G-751

[Svenn]

Well, I ordered 2 tubes of this stuff a while ago to try out when I got my new stuff. Now that everything but my Prom is here, I'm trying to decide what to use it on. The reviews I saw showed all the compounds running on air. I'm using a Prom and Water-cooling.

I'm just wondering should I use it on cpu (Prom), GPU (9700 w/ water + pelt), and/or NB (water)? The MCW50-T came with some arctic alumina and I have some arctic silver III lying around too.

I'll probably stick the Shin Etsu on everything, but I figured I'd just see if anyone had tried it on anything other than air cooling.

I have a bunch of Thermal pastes including this one as I am running long term tests on. I'll tell you one thing about this grease, its hard as hell to apply it, as it's like applying dog poo thats been in the freezer for a few hours.

Don't mistake what I'm saying as this stuff is junk, its not. It's just hard to apply. PS its not so bad if your running a AMD as the die area is small, for P4 users its difficult

I've tried the plastic bag method, credit card method, coffee filter method, jewlers trowel method. The only thing I won't do is heat it up prior as I dont want any inconsistincies in my testing.

I've gone so far as using 5 brand new identicle heatsinks so cross contamination will not be a factor. 3 more weeks before I am done with this craziness

[Tweaked!]

Hey SSS, have you tried heating it up some first?

[gobbo]

I've actually got some of that stuff, and i have to say that if you pop it in your case for about 2 hours before use it normally warms it up enough.

I put it inside our hot water tank room where it is close to 40C and after 3 hours it was just like AS3 in consistency.

Still waiting for it to have the 1 week run in to test it compared to AS3.

:p

[KAIN]

Why would it create inconsitincies? As it's the same as using the liquid it heats up and becomes a thinner consitency.

I've tried it, excellent stuff. But definetly need to hold it in your hands for a minute or two before use.

[alwayslate]

I completely agree on the dog poo consistency... pain in the a$$ applying this stuff.

I applied it to my XP1800 with a D-Tek TC4 water block. Works great. I estimate about a 2 degree C drop from the CoolerMaster something-or-other paste I had on there before. Then again, it was really only my third time applying AMD paste and mounting a block using thumbscrews so I couldn't tell if the diff was from G751 or from improving technique...

I think I have a pretty hot running chip. Not a stellar OCer but it will do at this point. Have it at 2GHz but at 2.0 vcore. Case is 32C (need more airflow) with idle temp at 42C. Yeah I know that's high. But when I back down to a lower speed like 1800MHz and 1.75 or less vcore then it runs like 3 degrees over case temp (i.e. 32/35) so the grease/mounting seems to work ok.

[Stepper]

I'm using that mess too...I've noticed that it takes about 200hrs to show any drop in temps...which on a box that U R alwayz tweakin...is nearly impossible...

[sjohnson]

Part of the Shin-Etsu mix is silver. My XP1600 suddenly developed a huge rise in temps last night - after running for over a week at "normal" temps - from 50 C to 95+ C (cpu diode temp). I tore the HSF off last night and found a spot of silver (at least, *silvery looking) concentrated on one spot of the core.

I must have applied it unevenly - used the plastic-wrap technique - or the silver migrated to that one spot.

[nikhsub1]

What we need to realize is that there is no holy grail in thermal pastes. It has been determined that no more than a 1C gain can be had by better (perfect) thermal paste to what is currently available.

[PiLsY]

Rubbish - theres a 10c difference at idle and 6c under load difference between the shin etsu (coolermaster premium - made by shin etsu on the tube) and AS3 in my prommie. AS is old hat - its not been improved to any extent in what, 4 years now?

You really do need to heat the shin etsu before you put it on though. It feels like dry clay otherwise. Just doesnt spread.

P4 2.8 @ 3.8 / 1.78v actual.

AS3 : -8c idle, 1c load.
Shin Etsu : -18c idle, -5c load.

Cheaper too. Arctic Silver is dead and buried.

PiLsY.

[Svenn]

How do most people apply thermal paste? I do what the AS instructions say. Thin even coat on the surface to be used on, and also rub some in on the heatsink or waterblock or watever on the spot where it touches.

[PiLsY]

I just stick a blob in the middle and let the heatsink/waterblock/evaporator do the rest. Always spreads it out evenly when you put some pressure on it.

PiLsY.

[NoEcho]

I have no profound love for AS but I disagree that Shin Etsu is going to give you anything like that drop in temps.

I've had ASIII and Shin Etsu on my P4. Temps were not profoundly different between the two. I won't crank anybody's chain by pretending to be scientific about it, I tweak and modify and have been letting the ambient drop with the weather. Both pastes are fine and neither is profoundly different.

It is hard to spread. Heating it might help but I don't think you want to heat any more than you're going to use. I think heat is supposed to activate some sort of change in it.

[KAIN]

I saw about 3-4C drop with Shin Etsu over Artic Sliver 3, but I can't say the tests are conclusive at all due to the huge amount of variables involved!

[PiLsY]

Well the performance of Arctic Silver pastes has always been less than stellar at sub zero temps. I have noticed that it always separates out into silver powder and clear liquid after a few weeks at -30 or so. It seems best at home at temps of around 20 - 40c, which to be fair is where most cpu temps seem to sit. At these sort of temps I agree there wont be much difference between thermal pastes. I have noticed about 4c difference between AS3 and the shin etsu on air cooling with my xp1800 @ 2183mhz / 2.2v on an alpha with low rpm fan. Temps were 62c under load with AS3 and 58c under load with the shin etsu. At sub zero though the difference is nothing short of miraculous. On my system the only thing that changed was the thermal paste. Ive remounted my prometia that many times that I always get the same temps at idle and load. Simple fact is with the shin etsu my temps are MUCH lower at the cpu and evap temps are noticeably higher, indicating better heat transfer. 10c idle doesnt affect evap temps as minimal heat load is being put on. It merely shows off the incredible thermal conductivity of this paste at temps of -40 and lower. Under load my evap temps with the AS3 were -29c @ 3.8ghz. With the shin etsu its -25c and the cpu temp is 6c lower than the AS3. Infact at first I couldnt believe the difference and reapplied the as3 to check. Got the same temps as previous with as3. Put the shin etsu back on and got the same results again.

Draw your own conclusions, but from where im sitting it looks pretty damn obvious that this stuff rocks. Theres a reason why all the top clockers use this. Ask Opp and JC what paste they use.

[NoEcho]

Sounds like you're saying Shin Etsu gave you a 54 C degree difference now. That strains credulity.

I like Shin Etsu. I like AS3. Maybe Shin Etsu is better for sub-ambient. On my ambient watercooled P4 there isn't much difference.

[PiLsY]

Sorry can you count?

[felix88]

he's looking at your evap temps.

did you really get such a huge jump in evap temps with such a small decrease in CPU temp? i'm a phase change newb, so forgive me if this is obvious.

[Hiwayman]

I want to try some of this stuff:)

Do you know where I can get some in the UK?

[PiLsY]

Hiwayman - pcworld, maplin, anywhere that stocks coolermaster stuff.

The shin etsu paste is the copper coloured tube of coolermaster premium and has "made by shin etsu" or something in small letters on the label. Costs £5.99 for a tube at pc world.

Felix - AS has never really performed that well at sub zero temps. I actually got better temps than AS using some generic white crap that came with a cheapy globalwin heatsink. The shin etsu stuff merely performs as youd expect it to. Its more a case of AS underperforming than this being th eholy grail of thermal compounds. Still, ive noticed a consistent improvement from AS over several different cpus and cooling combos, so it gets my stamp of approval.

[Hiwayman]

Plisy, Thanx M8. Pcworld would have been the last place I'd have looked.

[King_of_qb]

i don't know about anybody else but i have seen great gains from using shin etsu i get 42c under load win the shin etsu and now 49c underload since i ran out of shin etsu and have to use AS3

just my 2 cents

[gobbo]

Just got a tube myself, time to give it a try!

When i first tried this stuff it's like trying to spread pastry due to its consistency!

Pop it in boiler room for a few hours!

BTW, just noticed it says that it should be stored at 10C??

[xgman]

I can't stand the Shin Etsu stuff. I threw it out. It goes on like dry peanut butter and the thermal pads version falls apart in your hands. I'll stick with AS3.

[antipop]

Does someone knows where i can find some of those in europe?

[PiLsY]

Antipop - this stuff is Coolermaster Premium Thermal Compound. Its the copper coloured tube version (theres a silver one with standard white gunk in as well - dont get that one. The shin etsu stuff is grey) and has "Thermal Compound by Shin Etsu" written on the label under the coolermaster bit.

Pretty much any PC shop should sell it (they all do over here anyway). Where exactly in europe are you?

PiLsY.

[antipop]

I'm in france and i've been looking on the web and i didn't found any in france, i only found one in UK but they ask for £15 for shipping (it's not the coolermaster one)

[PiLsY]

This is the paste...
http://www.coolermaster.nl/pruducts/retail/products/thermal/ptk-001.html

You should be able to find it from any shop that stocks coolermaster.

PiLsY.

[antipop]

10x PiLsY but even the shops that sells coolermaster doesn't have any of those (i found the regular one in only one shop), maybe i'll go to a shop and not on the net

[Krizalid]

I thought the CoolerMaster stuff was an older compound... Supposedly Shin-Etsu has a newer one. Someone posted a link to a place with it a while back, but I forgot it.
