wich case is this?

Gigabyte Aurora.

doesn't effect temps though. flow doesn't either. only when you have a difference of 100gpm / 1200gpm It's all a bit too overrated.

just don't use thermal compound and lap your IHS and block as good as possible. I got rid of the compounds, and now my loads went from 62c to 54c. :S

im not a guru but isnt the purpose of TIM is to help heat transfer/conduction become more efficient? atleast thats what i knew..its been around for like for years.. i dont know..this may be a new discovery and tim manufactures havent noticed it yet..

its gigabyte 3d mars to be precise..

As NetburstXE, disruptfam and myself have above pointed out, this advice is arse. You're correct in that the purpose of TIM is to improve heat transfer - no surface is ever completely flat right down at the microscopic level; what may be flat to the eye or the micrometer will in reality be covered in peaks and valleys. Therefore, you do not get perfect contact between the IHS and the baseplate, and therefore, thermal transfer is less efficient.

The purpose of TIM is to fill in these microscopic valleys, and thus increase the area of the two surfaces that is in contact - and thus increase thermal transfer. However, if you're ham-fisted in your application of TIM and smother the surfaces in contact, you'll actually decrease thermal transfer - no matter the product, TIM is less efficient at conducting heat than perfect metal-to-metal contact, and so it will actually serve as an insulator.

Apply sparingly in accordance with the manufacturers instructions and remember that the flatter the surfaces in contact the less TIM required and you'll be fine, but above all else do not listen to dnb#'s advice here.

you guys are definitely right about the TIM, but can you explain why my temps dropped so heavily with just 2 flat surfaces on eachother? I can't but it works freakn great. And NO I didn't put too much or not enough TIM on my cpu / block. One thing is certain, 200gpm more flow and 4feet less tubing doesn't help you to drop the temps, not more than 1c thats for sure.

about the TIM don't listen to me and smoke your cpu. But I'll never use this peanutbutter again.

You've just contradicted yourself. Your temps are better without you applying TIM than they are with but your recognise the essential thermal mechanics that are working here - therefore you applied too much TIM.

You don't have a clue whether I added too much. I know I didn't, because I used watercooling for about 5 years. 90% of this topic is new into WC. and they definitely can't tell me how to get better temps. All the theoretic nonsense about flow for example are just different in real life. there are so many factors...

How else would you like to explain it then, short of a poor mount every time you installed your block using TIM? Magical temperature fairies temporarily suspending the laws of thermodynamics inside your case?

In any case, this is all a bit off-topic and really deserves its own thread. For your viewing pleasure, I leave you with...



Sudden tubing asplosion syndrome!

[Carey]

There's something very odd going on if you're not using and TIM there dnb. you must have the flattest surfaces ever and used 10000 grit paper to polish both sides!

Anyway, I've been snooping around for over a year now, and have finally decided to register. This is my first post, and what a way to say hi than to show you a pic of my build. More mods to come, but this is the first round on my new V1200B+. Loving the case.






Enjoy! Comments and suggestions welcome.

This can only be obtained by machine milling not by hand mate... secondly you got a swiftech block which are known to be almost 100% perfect, no need to sand there...as you prolly make it worse

a little bit of TIM is never bad...

But by the way nice build man, great job... same remark for Carey too... can we have more pictures form Down under

WOW

[knet370]

those v1200 are damn sexy.. ;-)

[dnb#]

I love the 120.2 cut on top. looks damn nice. can you post some more? I like it

[CoNMaN]

Carey nice

[the monk]

finally got the covers installed on my case......build a "fan cover" for the lower section.

dnb#, please tell me you lapped the GTX while it was bowed.

Blocks should NEVER be lapped, especially if they've been bowed purposely. Most (if not all) blocks today are machined flat (much flatter than you'll get it by hand), unless you have been lapping things for years as part of your job, you are more than likely to screw it up. Yes, it may be flat...but is it parallel?

My IHS + GTX the GTXs' copper was pretty dirty and definitely not even near flat. the IHS of my e6750 was actually better than i've seen so far imo.

I don't understand you guys thinkin that I don't know what I'm doing, probably better than the most in here have had 10+ al different setups included chillers and tec's. so I've had all the problems that are possible to run up to.

I bought the GTX because of this nice inner structure and mostly because it was proven to be nice and flat. Dissapointed me though. lapped it once, after 2 months in use another time + the IHS and now it's running great with a 120.2 BIS lite w/ 800rpm fans. 56c full stressed after 30 mins at 3.8ghz+ 1.475

aint bad isn't it?

[TedShred]

man there's some cool sh*t in this thread

@SoulsCollective: hope you found the escaped alien!

[inCore]

@the monk: Not bad, just a little bling for my taste. Somewhat ironically, I like the look of the radiator with the two 35 mm fans attached to it, looks like the back of a fighter jet

dnb,
sure you're pro and all that , mut what you're saying is just weird.

I mean, why did you even try to run your rig without thermal paste at the first place? That's like one of the dummest thing you could do. And lapping _that_ block? I'm not sure should I laugh or cry.

And don't let my post count and join date fool you, I've been in bussiness far longer that you might expect.


Good night to you all, I'm going to bed. It's 23:10 here and my girlfriend doesn't have blanket on. Nor anything else. Cheers!

waterlogged, if you have the time review this post.

the silicone chips we cool are real flat. except for the heat shield on the intel, for thats why people lap, as for any air gap has to be filled with thermal grease.....less grease the better. flat is a good thing. peace, randy.

I kept putting less and less paste on it every time. I seriously don't take all that theoretic nonsense with charts and stuff, do you really think a microscopic hole or bump will raise your temps up that bad? NO

a single postcount on XS isn't that important or am I missing something?
