Yea slowly just need to cut some caps out of Perspex to make end caps for the res and build a new rad box to fit 2 360's

Also LiamG6 did your 12715 turn up yet?

I suspect you will find that works much better than before. Props for using plastic as a clamping mechanism. From my experience heat transfer from the hot side to the cold side through the bolts was always a pretty big performance hit. As much as 10c. Looks good. thumb.gif

yea I was bit worried using is as could brake or crack easy but I did the bolts up tightly then put the bolts on after as they will be just used to hold it to something as the Perspex threaded lot better then I thourt it would

Yeah using perspex as the mount is a great way to insulate the bolts and keep thermal transfer to a minimum, looks beefy enough not to crack too. Awesome news re the 2 360 rads too biggrin.gif I wish I had 2 of them haha

Yes my 12715 just arrived yesterday afternoon, was very surprised to see it was all intact as they had just sent it in a very small envelope with a thin thin piece of bubble wrap around it. The last TEC I bought came packed in a box in foam and that was inside another box full of those foam peanuts, this one was just like an envelope haha.

I should have time to start doing the insulation on my motherboard tomorrow, I'll also cut down a piece of copper to make a 40mm coldplate and lap it. I think I will lap the TEC too, seems a bit uneven, I may have to lap my IHS as well, the first G3258 IHS was extremely convex, I'll check the TIM distribution when I pull the water block off to see if this one is in need of lapping. I think my Apogee XT water block is very flat but will check that too. I have some 2000 and 3000 grit lapping sandpaper so will get stuck into that tomorrow. Hopefully nothing needs serious lapping otherwise I'll have to get some different sandpaper.

Do you guys put di-electric grease in the CPU socket? How much and how do you apply it without damaging the pins? Also should I delid the CPU and put better TIM on? I have Liquid ultra here already. Also if I delid would it be ok to coat the top of the CPU substrate where all the capacitors are but not the die in liquid electrical tape to insulate all those capacitors? Or is that a bad idea? I've never seen anyone use LET on the CPU substrate, but don't they use nail polish or something on the capacitors when they delid Haswell CPU's to stop the IHS shorting them out? I figured if they are in need of protection from shorting by the IHS then they would also need to be coated in LET to stop any condensation shorting them out. Or is LET a bad option for that?

I'm tempted to delid and lap everything to get this puppy as cold as possible, I like efficiency so its seems wasteful not to put the extra effort in to get the best result out of it.. The only reason I wouldn't delid is if you think it opens me up to issues with condensation, but I'm already worried about condensation forming under the IHS without de-lidding as I believe Haswell IHS is not airtight right?

none of my PWM controllers will arrive for another week or two so I'll be running this puppy at 12v ~11.5amps and should see 30-40*c Dt from hotside waterblock temp at 100% load on this little G3258. Hoping that's good enough for 0-10*c core temp but I don't think It''ll be that good biggrin.gif the only way to get it colder though is with a 15v PSU and a larger 225w 40mm TEC so this will do me for a while, already spent too much on it, all in the name of fun though.

That's great news I want a screen shot wink.gif also I delided my g3258 doing the vice method and it was easy I used clear nail polish to cover the caps BUT! It's putting the lid onto the cpu in the socket mine slipped out the holder and snapped the die in halfs that's the scarey part.. and stuck some vasilen around the pins and socket and it was fine I also coated the motherboard front and back with clear nail polish before insulation but then I powered it on and it never worked lol

liquid ultra has a freezing point around 8*c I think so get some asc same as they use on dice or phase for any where in the cold side then use as7 or diamond or something on hot side for max transfer

bummer, I spent $15 on the CLU lol, I'll save it for another CPU. So you think LET on the FIVR capacitors is a bad move? Just use nail polish?

I just bought some thermal grizzly kryonaut, that should do me very well for the CPU die, IHS and the TEC too, seems easy to spread, it's designed for sub zero temps but performs very well at ambient so it will do for the hot side of the TEC too, albeit a bit expensive.

I'll have to wait for that to get here so that will delay me until probably next Monday night, but I'll need quite a bit of time to delid and lap the IHS, Cold Plate and TEC anyway so that will keep me busy over the weekend. Plus applying LET to the front and back of motherboard will take a while. I am pretty dubious about putting dielectric grease in the socket but I guess it has to be done, just hope I don't stuff any pins in the socket. I'll put some rubber art eraser in the centre of the CPU socket where the capacitors are, I'll also put eraser on top of everywhere that I put LET on the motherboard and I'll cram it in around the CPU socket after the CPU is in place too. Finally I have some neoprene that ill stack around it and put on under the backplate. I'll cut some neoprene to fit snugly around the TEC on the water block and hopefully hold it all in place in the centre and prevent too much ice forming in there.

To avoid cracking the CPU die I've heard you can loosen the bolts holding the CPU socket clamp down. Loosen the socket bolts, put the CPU in socket, clamp it down while holding IHS in place to stop it sliding and damaging the die, and then tighten the socket screws down again to apply the correct pressure to the CPU in the socket.

I'll document the whole process and put up a thread on the TEC section when its done. Wish I had everything here already so I could just do it all over the weekend.

I thought about buying another 240mm radiator but I'll wait till I see how my current setup holds the hotside water temps before pulling the trigger on that I think, technically I'm dumping about 200w of heat into the loop at full load from the TEC and CPU and I have 360mm of rad space, it should hold that pretty well, but I have 1200rpm fans so another 240mm might be necessary to keep my hot side as cool as possible.
