CPU getting really low temps.

So i just recently purchased computer. I built it installed windows and everything. So far its running great, i was just wondering if you guys could give me your option on my CPU temps

CPU- AMD Athlon II X4 640 Propus 3.0GHz

HEATSINK- Spire Thermax Eclipse II


I have the CPU running at 3.0GHz as advertised (I turned off the "green power saving" feature, now it always runs at 3.0GHz). I would like to overclock it but am unsure as to how to do so. I am using CORE TEMP for tempreture readings, and the tempreture of my CPU is 13-15 Celsius constantly highest i'v ever seen it is 19 Celsius. Am I really getting these low temps or, is it a fault with the program i'm using?



Many thanks,
Edvin

Try downloading HWMonitor.Look at the CPU temps and see if it's the same as CoreTemp's.
Don't think those temps are right but they could be.15c is 60f.Usually the CPU is never colder than the room temp.
What is the room temp?

Just installed it. It also says 14 Celsius . So does that mean i could overclock my AMD Althon 640 insanely?

I have not stressed the cpu at all. I just haven't had the time, and why isn't it possible? its in the basement of the house. How can i tell if the sensors are calibrated wrong? What do you recommend i do to stress it?

I do not believe it is D: I was strapped for cash and bought the best cpu at that price point. What do you think a reasonable over-clock would be if the temps really are 15 Celsius. Well upstairs its like 70 but i'm not exactly sure about the downstairs.. Well the fans on the heatsink both run at 2325 RPM , and the intake fan runs at 1312 RPM. All i know is that all the CPU temp monitoring things i'v tried give back 15 Celcius. The motherboard itself when i go into bios reads back at 17 Celsius.

well, i'm running it now on torture blend test. The highest temp its gotten to so far (30 min) is 24 Celsius.

IT actually went down to 23 Celsius. I did the maximum heat one....

ok, when i ran the blend it went from 15C to 25C. when i ran the maximum one for about 12 min it went from 15C to 24C. I do think that my temperature scales are correct though, the cooler is rated number 1 on frosty tech.

Thanks . So the temp is normal and i shouldn't be alarmed

Where do suggest i should go for more opinions? so 15C ideal is amazing?

oh okay , thanks for your help. i was worried that it might not be running how it was suppose to and thats why it was so low

you should know the farther you are away from the tj max the less accurate your temp readings it will show below your ambient but that isn't actually physically possible (due to the rules of thermodynamics) good temps i'd go for 3.7ghz+ yeah!

If you are looking at the core temps I have found them to be inaccurate, the computer I am am typing this on says 11C when the room temp is around 20C but in Hardware monitor it give a CPUTIN temp which reports 26C which I think is more accurate. Do you get both core temps and a CPU temp from the motherboard sensor? (BTW I am using an Athlon x3)

I get

Temperatures:
TMPIN0 17C
TMPIN1 24C
TMPIN2 94C

and for the CPU temps i get
15
15
15
14

All from CPUID Hardware Monitor

I touched them both, the SB feels jsut a tad hotter. Neither are hot enough to hurt my finger though. Do you have an idea of what the 94C might be?

I ordered brand new parts. How would i tell if the sensor is wrong?

can you do a print screen shot? those are really low temps...

Hes got HWMonitor.The CPU temps are dispalyed seperatly.All those TMPIN temps are the mobo temps.

What about the other temps?

I'm leaning heavily toward an incorrect sensor. a CPU temp of 15c = 59f, and the 13c you mentioned initially would be ~55.5f.

Basically this means the room your PC is in has to be under 55f, which even for a basement is VERY cold. As in You'd be wearing at the least heavy pants and a sweatshirt, if not a jacket, cold. You basically would have to have the windows open in an unheated basement with an outside temperature below freezing for at least a day to get the room that cold.

For reference, I'm in a basement with no heat, and an open window to a roughly 45f outdoor temperature, and the ambient is roughly 66f. My CPU's idle at roughly 29c (27c in the dead of winter when I can get my ambient down around 60f) Now I don't have quite as high end a cooler as you do, but I have a mid-range aftermarket, and my CPU's TDP is 65w vs your CPU's TDP of 95w.

You're 26c Prime run also leads me to believe something is off. I don't suppose you actually placed your finger on the CPU heat sync during that run? if your CPU was really only 26c, it shouldn't even feel warm to the touch.

Actually, 94C is around 210F. -GreyFox

Well I would say that if your cpu temps at first seemed unreasonably low, and that faulty/non-existant 94c temp seems unreasonably high, then you have a faulty sensor or two. What is the make/model of your mother board?

A long time ago I already said it was the motherboard.The sensors are defective or broken.

Is it that serious of an issue? Would it be affecting my performance if those temp thingys were off?

Okay, I really don't want to be without a good computer for a a couple weeks. I might rma it if they send me a new one before i ship mine back.

I honestly didn't mind that much.. just a little cause even my 6870 is under 60C even when its on full load

I know that, I was giving a comparison. I think I will thanks for the help guys.
