CPU Temperature Monitors Only Go To -13C?

[yogurt_21]

Sounds like it could be one of two things to me...

1. Your evap to CPU contact is very bad, what does the evap temp read @ under load?
2. Your SS was tuned for very low heat loads, its not normal for a SS to hit -74C. Even my big 2hp SS only hits -60C unloaded (but was tuned for massive heat loads).

Sorry if I missed it, what are the specs of the unit (eg compressor, condenser). A few pictures of the unit as DOM asked for would help.

it sounds like you might be running a badly tuned unit or your contact is bad.

I have my modified vapochill classic tuned for heatload as it was designed to run athlons (yes just plain athlons, not athon xp's, not athlon 64's, not athlong x2's, just plain athlons)
due to that ti took a bit of tweaking to even hit a 150w load capacity.


the 2 main prebuilt units around during amd's 939 socket were the prometeia mach 2 and the vapochill lightspeed.

of the two, the mach 2 was more temperature tuned while the lightspeed was more heatload tuned

if you have a prebuilt I'd guess it was the prometeia mach 2 based on what you've described thus far.

but it's entirely possible you have a custom unit in which case we'll need the actual info off of each componenet as fatguy and dom have already said.

I don't know what the specs of the compressor or condenser are (this is a used unit, and other than pics I am unsure how to check; I think there is a label on the compressor, but the condensers don't have anything that I have seen). I am posting some pics now.

 

[NinjaNife]

These are some pics that were sent to me by the seller (I had asked for some measurements, which is why the ruler is in some). I could take more recent pics, but it looks exactly the same now as it did in these pics. If you are looking for something more specific, let me know and I will try to get some other pics.

 

[DOM]

the only thing i can think is it needs to be re-tuned for a heavier load

i hope you got it cheap

I believe that this is the "Prometeia Mach 2", but was modded (the seller told me something like "majorly modded by Chilly1"). What was changed I am not sure. I do know that the display on the front says "Prometeia" when it is first turning on, which is why I am guessing it is a "Prometeia Mach 2". So I guess this might count as possibly a pre-built and a custom lol.

If you need anything else please let me know.

How hard is re-tuning? Or how expensive would it be to have someone who knows what they are doing work on it


*EDIT*
Forgot to mention about the pics.. The "NO SHUT DOWN" is always on there, and doesn't seem to be anything other than possibly a glitch. My power cut out last night, and when it came back on the "NO SHUT DOWN" was gone and "NO MAINS" had replaced it. Not sure if that means anything either, but everything (compressor and fans) are running fine, so I just ignored it for now.

Here is a link to the thread where it was for sale (I talked to cdawall in a different one of my threads, and ended up buying it from him after a lot of PM's).

so how much was shipping ? and i saw the guy that modded it Chilly1 seems he owns ppl money over at XS

but i only know 2 ppl that can retune it for you the one that made mine and runmc over at XS

Shipping was about $65.

Could you clarify the "and i saw the guy that modded it Chilly1 seems he owns ppl money over at XS" part? That doesn't make sense to me (confused by the wording or something). Who owes people money? Chilly1 or someone else (and did you mean Chilly1 didn't mod it, someone else did, or something else)?

Do you have any idea how much it would cost to re-tune ($50-100, $100-150, $150-200, etc), or do I have to ask one of those guys? Thanks for your help.


*EDIT*
I wanted to clarify that I am very happy with this unit. Although it may not be completely perfect for my setup, it is still working better than air or water, so I am happy. I don't blame cdawall for any of these issues (I know a unit made for an AMD 939 isn't supposed to work on an Intel 1156, and the temps I am getting with this are still pretty decent, at least for mE). Just thought I would put that out there

 

[DOM]

on cdwalls f\s thread he put that Chilly1 is the one that modded it, and over in xtremesystems.org i guess something happened he kept ppls money and units he was supose to retune or work on so thats why i said to ask runmc how much he'll charge to retune it i hear his a good guy to work with

cuz if it was me i would sell it, if its going to be to much to retune cuz its like 100+ just for shipping then to get it tuned for higher load

So did cdawall or Chilly1 keep people's money and units (still kinda confused lol).. I will PM runmc later if I remember. Thanks

You need a K-probe installed next to the IHS (underneath the cpu slot cover) and a Digital Thermometer to have accurate temps:

....

Once you go subzero there is no way on using mobo sensors or software.

Would you mind giving some links to exactly what you mean (the probes and such), or tell which brand/version you recommend?

 

[fatguy1992]

From what I can tell that compressor and condenser should be good enough. So it looks like it was tuned for low heat loads. A new evap would also help a fair bit, that one looks like the old ordinal one.

 

[yogurt_21]

depending on what you have around locally you may be able to take it down to a local A/C shop and have it tuned for you there. it's up to the shop on what to charge, but I had a freind get his vapochill XE overhauled for 100$ and it now runs better than any prebult I've seen with a -30c head temp with a 200w load. Being that the XE's we're designed for a 180w load at -5c Coolant temp that's not bad at all.

 

[fatguy1992]

What do mean by prebuilt? Vapochills etc or ones made by phase builders from forums etc?

they where prebuilt like the ocz ones but idk if those even made it out to retail

but builders modded them for the ppl that got them and they couldnt hold them temps or wanted them colder idk i think they where out before i knew anything about comps that was in 05 lol

How would I describe it to them though? Just "tune it" or would they know what "tune for a 300W load" means...

Off topic but what are you using to insulate your board there?

Haven't seen that before.

they wouldn't specifically know a rated heat load target on the coolant head but they can maximize the efficiency of the unit with the best coolant for the compressor, possibly replacing the condensor, chaging the rated voltage settings, etc. The unit is just a mini-refrigerator, they'd know exactly how to boost cooling performance without necessaryly knowing what heatload it could handle.

What do mean by prebuilt? Vapochills etc or ones made by phase builders from forums etc?

the prebuilts were stand alone phase change units made to be moutned onto the cpu by a manufacturer. The main two I poster were (Asetek) Vapochill and Prometeia. These manufacturers specialized in these extreme coolers back in the day. Lately I don't think either is making these units anymore, (though vapochill is still making water and aircooling products).

now phase units and peltiers have been used to cool machine and radio components for 70+ years. Many modders make their own units by either taking apart old A/C's or refrigerators, or by simply buying the individual components and then turning them into phase units. These guys don't stop there though and continue to make dual phase or even triple phaseunits some of which can rival the cooling power of LN2.

the prebuilts were a niche market that simply wasn't profitible those who had 800-1000$ to spare for a unit, could just as easily pay a modder for a dual phase unit that offerd twice the performance.

http://www.crazypc.com/products/9290GT.html
this is likely the OP's unit but his has the optional Lian Li case mod as seen in this review. http://www.xbitlabs.com/articles/coolers/display/prometeia-mach2gt.html


http://www.octools.com/index.cgi?caller=articles/asetek/lightspeedl/lightspeed.html
this is the vapochill lightspeed, the last phase unit vapochill made they started with the classic and made some modifications to it along the way (XE, PE, etc) and then put this out in 04.

being that they were released that long ago, neither were made with quad core cpu's in mind. This is why modifications are necessary.


edit: ah so this is why the vapochill line was discontinued

I believe he is using Dragon Skin (might be wrong but that is what it looks like). It is a silicone that is normally used for Hollywood movie special effects, but also works as an insulation/sealer. Here is a link: http://www.smooth-on.com/Silicone-Rubber-an/c2_1115_1339/index.html

I know I wasn't asked the question, but even if that isn't what he is using this stuff is worth checking out
