My chiller experience was tossing the rad outside in 10 degree F weather lol.

Never got frost.. but my house is not insulated well.. Only hit 0C on the software probes.

Personally... I would freeze the CPU and get what you can out of the GPU. only cause of hwbot. GPU just don't scale like CPU under cold. Problem is no one cools the whole card... you can expect the rubber whatever to eventually cool it all but it aint like a full cover heatsink or something...

VRMS get hot still... (VRMs on my 4890 totally limit the clocking ability) I am not a GPU ln2 colling guru though.

(You take that mass versus responsive ness argument and apply it to rubber .. yes rubber cools the whole card but it aint really KEEPing it cool... )

I do have 3 x EK FC-4890 full cover blocks. VRMs should get nice and cool with those if I did go that route. You're absolutely right about the VRMs getting the hottest.

I'm just going to go with air for now I think. It'll be fun to listen to the power of all 3 of those fans going........get drowned out by the sound of the compressor In the meantime I can look for a DICE pot, and get everything nicely insulated.

EDIT: I ordered the Dragon Skin

Hopefully it will get here by Friday when I get home from work....it's only coming from Pennsylvania I think.......at least that's where the address on the website is and my money went.

EDIT: I also plan to do something very close to this when I get home from work (hopefully Thursday night).

Sounds like a masterful plan

[ny_driver]

Well I received the Lizard Skin in the mail and I think tomorrow I will apply it, insulate the block, and set up the new loop.

Stay tuned for more pictures.

Right on, popcorn!

Very important questions before I actually go ahead and hook up the chiller today.

I know I asked about this before, but what about the actual cpu socket? What do I do to protect the pins from getting frost? I just read that dielectric grease will melt silicone rubber over time.

When covering the back of the board, can I do the entire socket area or the whole board if I want?

Thanks again Overclockaholics.

Rule of thumb for me if it is going to be a daily sub-zero setup (24/7) then grease the socket. If not then don't.

[ny_driver]

There will be lots of times I do not even turn on the chiller (EDIT:...probably NOT), as cold as the res gets.

I usually use the computer Fri, Sat, Sun and am away at work the rest of the time, Sometimes however, I have weeks off and the computer gets used everyday.

Better safe than sorry I guess. How fast do you think the grease will eat the Dragon Skin, and does that really even matter?

EDIT: grease is pretty permanent right? No way to get it out of the socket?

[DrNip]

You will need grease if you don't plan on unhooking the unit on a daily bases to air out is what I am saying. Even if you only plan on using it a few days a week. It isn't permanent but a bitch to get all out. Be careful not to damage your pins.

If you have to rma the board you can wash it out... otherwise nope..
