CPU Temperature Monitors Only Go To -13C?

[NinjaNife]

i think the best way your going to figure this all out is to invest a little on a temp sensor that will go down to the negatives you need and stick it in the cpu socket right next to the cpu that should tell you exactly how hot or cold its getting. my thought is the temp sensors just arnt reading correctly

Do you have one in mind? And how exactly do I put a temp sensor *in* the CPU socket without unseating the CPU.. Or did I misunderstand?

this at least will get you down to -20c to let you know the thing is in the subs

as for were to lay it

theres actually a little gap underneath the hold down bracket to the left of the top right hand screw on the socket that you could stick that sucker in and that would give you a pretty accurate guess on how cold the cpu is

i got a volt metter / temp gage from sears craftsman not the best temp gage but it came with a probe i put it on the side of the ihs from he cpu

it was like 30 buck i dont remeber

So you mean between the CPU clamp/bracket and the CPU, not between the CPU and the socket then correct? So you are measuring the temp of the top corner of the CPU?

yup you got it.

 

[NinjaNife]

Hmm... I will have to look into that. Thanks for that.

 

[DOM]

did you insulate your motherboard?

 

[Arrakis9]

make sure to hit that thanks button on everyone that helped u out

lol I always forget that sorry It is fixed now

did you insulate your motherboard?

Yes I did.. I used Vaseline in the CPU socket, and Art Eraser around it and Neoprene on top of that and on the back of the board (insulated for 24/7 use). Spent like 5-8 hours doing it on the floor :/ My back was killing me lol!

it takes me like 20mins

but idk about the phase it seems like its tuned for light loads mine only gets -50's C idle and -40's C load but its the evap temps but it was made to hold 300watt load in the -40's

and on my i7 920-980X my temps go above 0C on heavy loads

You should insulate mine for me

Yeah the evap temps (or whatever is showing on the digital readout) always stays between -65C and -75C. That is with load and without. What are your CPU temps with load? Does RealTemp or whatever you use still give a negative value, or do you get a positive value like me (even though the evap stays negative)?

 

[DOM]

if its showing that cold and doesnt drop with load im thinking its not on there right or the gage is wrong

mine shows -XX it doesnt start moving to the 0c+ on the cores untill i get in to the 5GHz range on load

I guess I had better get a new temp gauge then.. I am not sure how to check if it is on correctly or not though... I am using a homemade mount (temporarily), but it has a square plate on the evap and it seems to be solidly on there (I have remounted it 2-3 times with the same effects, and the thermal compound has always been evenly distributed over the CPU). I wish that the problem is just that I mounted it badly, but I can't see how that would be possible unless the amount of tightening on the screws makes much of a difference (I put it pretty tight). Is tighter better or worse?

 

[DOM]

i put mine the tightest it goes but what kind of paste are you using ?

I have just installed my first Phase Cooler and am using RealTemp and CoreTemp to monitor my temperatures. However, both seem to stop monitoring at -13C. Is this a limitation of my hardware, or the software itself? If the software, what program goes past -13C? I have a digital readout on my Phase unit and it says -74C, but I know that is the evap temp and not the actual CPU temp. I am using a MSI P55-GD80 motherboard. Any ideas?

just an fyi -74c is the coolant temp in the phase unit, not the temp of the coolant head against the cpu

typically unless you're runnign a dual phase unit (ie phase 1 cools, phase 2 takes the already cooled coolant and cools it further then it passes to the head) you're not going to see -74c on the coolant head with a heat load applied.

Okay thanks for that. That definitely makes sense.

Hey I was just thinking... How can the temps I am seeing be the coolant? Unless someone somehow drilled into the evap, how would they be able to get the sensor in.. My probe cable is wrapped around the outside of the hose, and disappears into the clamshell. Does this make sense to anyone?

idk how it can it must be on the evap, like i said its seems its not ment to take heavy loads ss phases can be had to be colder for like super pi runs etc light loads

 

[NinjaNife]

I am not sure the exact load it was made for, but I was told that it is designed to try and hold around -75C or so, and made for 24/7 use. I believe the original cooler was built for an AMD Athalon (possibly 939 socket), but it has since been modded by Chilly1 (as far as I was told) and was since used for larger loads (the previous owner used it on an AMD Thuban). It seems to be working pretty well, but I am somewhat worried about the CPU running at positive temps. Is it bad for the Phase unit if the CPU is running at positive temps, even if the evap is at negative temps? Will that harm the unit or CPU?

 

[DOM]

did you ever say what speed the cpu is at and what volts ?

it it doesnt get to hot eveything should be fine

 

[NinjaNife]

My CPU is stock 2.9GHz (auto volts, not sure what it is), and I had it overclocked on air to 3.6GHz at 1.275V (35-45C idle, 65-75C Prime95 test, possibly higher). Once I got the Phase cooler on, I upped the OC to 4.0GHz at 1.3V. Using Prime95, I got (4.0GHz 1.3V) temps around 40C (positive) with the Phase unit installed.

 

[DOM]

something isnt right those temps seem high for a low oc on a ss

have you tryed starting the ss up and see if the evap frost up ?

can you post a pic of the ss

I believe that I overheated the CPU when it had the air cooler on it, and because of that the temps are higher.

I have started the SS up without it being on the CPU, and frost starts to form within 30sec or so. Within 5min there is a large amount of buildup normally (depending on the humidity).

What pic would you like? I mean, a pic of the evap or something? Or just an outside one (like the case)?

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.
