impossible cpu temperatures

Hi all,

I recently installed a corsair h60 on my stock 8350 and since then my cpu temps in HWmonitor, coretemp etc.. have gone wonky.

i get readings in the range of 11-13c, regardless of load. sometimes when i start the monitoring program the temps will jump up to around 19cc and then fall to 11-13 and stay there. obviously this is impossible when it is 30c outside.

everything seems to be running fine, but i don't like not knowing what my temps are and i'm wondering what could have caused this/ how to fix it? could a misplaced waterblock cause such numbers? is it possible i damaged the sensors?

If you mean it is 30c outside of your house and room temperature, then it's fine because watercooling gives a huge difference from using a stock air cooler. Your temps are probably what is being shown. I can't see what else you'd mean but I think it's fine. If you want some extra piece of mind, just get a cheap temperature monitoring device for the front of your case and you'll eradicate the need for HWmonitor and get your problem solved at the same time.

Regular water cooling will not bring your temps below ambient temperatures. How would that even be possible?

You'd have to have a high end evaporative cooling setup with an external radiator running lines into the cooling sinks inside the PC case...it can be done...but it costs a lot more than H60i money.

EDIT: Here is a "guide" of sorts to building one such contraption, but keep in mind, you have to make sure your lines don't have condensation build up as water dripping inside a PC case is bad juju.

That is why I put "regular" before "water cooling" in my comment.

I think you misunderstood. I wasn't saying it would cause ice to form or anything like that, but it's way better than air. Just bear in mind that I'm actually not using watercooling at the moment.

You said that his temps are what the readings show. The readings show that the temps get as low as 11C to 19C and the room temp is around 30C. It is not possible for his temps to be lower than room temperature while using an H60i. Also, closed loop coolers are not always better than air cooling, let alone way better.

First of all, I said probably, not definitely. Second of all, air cooling keeps my processor cooler than room temperature, and water blocks are better than most, if not all, stock coolers.

1. Okay, but you suggested that it is possible, and that's the point.
2. No, it does not, because it is not possible, unless you're blowing an AC directly into your case, in which case, it won't get any lower than the temp the AC is giving out.
3. Sorry, I thought you only said air cooling, not stock cooling.

No... just no. Stop talking crap.

Well as (I think) I stated earlier on, my processor is 11c idle. My room is constantly 20c, give or take one or two. Until you know the specifics about my setup, don't tell me I'm talking crap. I will always know more about it.

That maybe so, I was going to get some temperature monitors anyway. I'll reply to this and let you know if you like. It has a fan by the way, you do know that right?

Okay Hailz. I would listen to iHog and 8350Rocks.
You can know a couple of things for a fact.
1. You can not cool a system below ambient temps using a stock cpu cooler or a regular water cooler.
2. AMD cpu temp sensors have a negative offset and that makes them report wrong(way lower) temps.

Now, the negative offset is a term more popular with developers who write programs like coretemp, speedfan etc. Maybe these programs are not well calibrated for AMD cpus or maybe AMD works with a bad batch of temp sensors no one knows that bit exactly but I am absolutely sure that these cpus report below ambient temps.

My room mate's 8120 reports 21-23 C on all cores (AMD cpus have a single diode reading out average temperature across all cores) on a stock cooler with the ambient temps in the range of 35+ Centigrade.

The only thing I find odd is that your temps are not jumping with stress loading which should ideally happen. perform a Prime95 run and let us know whether your temps spike up or not.

good luck

I did, then he tried to tell me I know nothing about my setup.

Nathan, you may be honestly sharing the temps that your system is reporting and I do not doubt that, but I can assure you that it is wrong. You would see a lot of people with Intel and AMD builds using the same cooler, say a hyper 212 evo and you'd be amazed that the AMD systems (FX series) will report lower temps than ambient but Intels would be more realistic.

I've already shared the reason for this in my earlier post.

Yeah and I said that it may be true, and that I will post realistic ones when I get a temp monitor, but apparently that isn't enough.

You claimed your air cooling was cooling to a lower temperature than the ambient temperature.

You said this:
