Build Log - Corsair Obsidian 900D

[Chaosphere]

Yup, after looking into it, and discovering my dad has a proper mounted metal vice, I am going to use that method. Going to do exactly as you did, including the nail varnish to protect the capacitors. Just a question, do you know where I could get a good sort of brush to apply the liquid metal stuff with?

Also going to do a small before and after comparison, with all bios settings set to default/auto, just to see what difference this makes to stock chips. Not going to bother fiddling much with OCing yet, as *hopefully* it will be a different ball game after this de-lid...


@Tut, I will film it if I remember for your amusement


Edit - Oh, and by the way TL, I built all of this inside a 350D. Its likemy PC is the baby brother of yours I think

The manufacturer video used a cotton bud and so did I!

Ok I got excited, and have now taken the lid off! Used the vice method and it came right off with a few whacks. All looks good so far, so fingers crossed.

Just now trying to get the black gunk off of the chip.

The 350d is a great case I love mine

Good job! :thumbsup:

It sounded a lot harder than it was in reality, right?

[Chaosphere]

Yup, by far the hardest part so far is getting this damn glue rubbish off!!!

Im slowly going at it with a combination of a scalpel and my fingernails

Shame I will have to wait now for the liquid metal to arrive... curse my impatience

[TeaLeaf]

I scraped off the big chunks and then used a normal TIM cleaner to prepare the surface nicely for the nail varnish.

[Chaosphere]

I've got most of it off and am now just going to slap some nail varnish on the capacitors

[TeaLeaf]

I masked off the area before applying the varnish to ensure none got on the core.

[Chaosphere]

I masked it off too, but still managed to get a tiny amount on the core. That said it can't really do any harm. It's a tiny spot just on one of the corners. Either I will use a q tip and some Polish remover before I put the liquid metal on, or just leave it. If the stuff isn't capacitive it can't hurt anything.

Sorry for all these posts.

Cleaned up the die with a q tip and alcohol. Now just a good layer of polish over the capacitors. May put another coat on before i apply the liquid metal. Hoping it arrives tomorrow.

Dont appoligise it is of interest to the community.  Now where is the vid

[Chaosphere]

Haha, in my enthusiasm I forgot to take it

I have some (rubbish mobile phone camera) pictures, but they are basically just the same as TLs.

Only other thing of potential interest is the temp difference I see... I ran a sandra system stress test / benchmark before the de-lid, with motherboard set to fully auto, and the highest temp was 98 (all cores 96-98). Going to re-run the same test after and see if there is some improvement...

[Chaosphere]

Liquid metal and arctic silver 5 arrived today. I'll just say that the liquid metal stuff is easily the most annoying thermal material I have ever used, and I have used a lot! I did the same as you TL, using a cotton bud - I think mainly because trying to spread the stuff any other way would be just impossible.

I ran the same benchmark suite I did before, and the hottest core was 62 degrees.

Yup, 62 down from 98. That is a 36 degree difference!!!!!


Now, of course I didn't control room temperature at all, and I didn't pay attention to the temperature at idle either time, but even if we assume the room is COOLER now, it would only add a few degrees on, so you're looking at a 25+ degree difference for what was pretty simple (if a bit scary!). Can't wait to overclock this thing now. I now have lots of headroom to play around with!

Hey mate what bench program are you using???
