Evap head pic

[Tingle]

Hi,

I have just got my mach2 installed and it seems to be rather hot :(

Currently with the evap temp at -45C the CPU temp is 3C

Seems rather a large difference when I spoke to someone, using the same board and same BIOS who had an evap temp of -40 and CPU temp of -5, both of us using artic ceramique

I am not quite sure that I have put the thermal compound on correct so is there any chance someone could take a pic of their evap head and CPU core so I can see what it should look like with the core imprint and compare it to mine

Seems a little high to me :(

well it sounds pretty close to right...

let me explain.

the unit is cooling actually perfect.and you are lucky yours is ready about right temps.
the cpu reading well....the nforce doesnt read from the chip diode like some boards,so it reads from a thermistor in the socket.
now i am sure you used a heater on the back of the board and that really makes the cpu temp read high,even if you dont it still is never close to the display temps.

now not to say you may improve your temps my reseating the head ..but...you are pretty close it looks like to the right temps.

is your friend useing a heater on the back,and are you? that could be the differnce in the 2 temps

welcome to the xtreeme...:toast:

[serialkiller]

think the temps are right,
I have about 5° on my 8rda3+ with 1.9Vcore (MBM reading from socket diode) and this is with Mach II filled with R507

Hi,

Thanks for the replies, my friend is actually Marci from over-clock, he got his unit the same time as me and is using the same board and BIOS so you should be able to compare temps from them.

When it says apply the AC thinly, how thin is that? So you can see parts of the core through it or so there is just a white covering all over?

Also, on my water kit I often saw temps of 40C, am I correct in assuming that it would cause no problem if I were to see similar temps on my mach2?

Finally, you mentioned the heater, I have neoprene in the back part to fill the cavity, the heater does get burning to the touch. Is it ok to remove it? If it doesnt improve the temperatures at all then at least it is going to help my system temp.

Another thing I just thought of that may affect it is I filled the underside of the CPU with dielectric grease, i.e. covered the thermistor in it, not sure if that conducts heat well

Thanks

Tingle - got a question - is 2.76ghz the max on your cpu ?

[Tingle]

No, I have had it running higher, running at 200*13.5 currently just to burn it in, no problems at all so I would have thought it can go alot higher

[bowman1964]

yes you can disconnect the heater from the back.
that would be a good way to se if that is causing the problem.

you only need the heater if you have condensation problems.run it without it and just watch for condensation.

[Tingle]

How do you watch for condensation when its sealed up inside?

I am missing something here i think :S

[bowman1964]

well you will see water droplets,but if you seal off the air from entering you cannot have condensation.that is all the dielectric grease is doing,and the silicone.it is just sealing off the air from the cold componants,no air touching componants =no condensation simple.:D

[Tingle]

Maybe this is an appropriate time to ask something I have always wondered!

I have sealed off both the top and the bottom, however, inside is still some air (they are not filled completly with grease). So, whats to stop that air condensing and causing trouble?

I understand about getting condensation on the outside, what I wasnt sure about was on the inside - does that actually happen if you have it sealed off correctly?

thanks and sorry for my stupid questions!

stupid questions.....THERE IS NO SUCH THING AS A stupid question..:D

you are right it is possable to trap moist air in a inclosure.you can if you really wanted to be sure,just get a can of compressed air (like used to blow off keyboards and such)and right before you seal it down....blow the air(which has no moisture) under and all around the head before sealing it down.thie will push the room air away and give you a nice moisture free instaltion
