Varying Temps - Page 2

post #11 of 20
HI PSULions.
Sorry to hear about your lil temp probs here.

The only thing I would question is whether or not the BIOS actually uttilizes 80% of the CPU's juice.
I dont know that to be true at all! I know the CPU to be IDLE in BIOS!.
The CPU's processing is SOOOO limited, - just your keyboard inputs, and abit of data variating (displaying your changing temps). Its processing nothing else!
Even in windows when we say we're "idling" the CPU is doing more work, as their is a myriad of background processes.

Dont think I'm attacking you - but if you know this to be true, and can give me a bit more insight into its truth (something to read maybe) I'd really appreciate it logan.


Take this bit of advice though lions, your bios is never wrong lol. - not unless you have a faulty thermometer I would say - and I've never heard of such a complaint.

MY suspicion is that your HSF isnt seated properly.
You reseated it I know, but there's the possibility that you still havent seated it properly.
Added to that, you say it feels cooler than 62c, which would make sense;- the sink isnt seated properly, and so the heat isnt being dissipated from the core/HSF tot he sink as it should.
The CPU is burning - but the sink doesnt FEEL hot - its not!

I really believe you have a seating problem - or poor case ventillation.

It would concern me that your Idle temps in bios (as I subscribe to ) what be that hot!
That means that your load temps are mucky man.


What is your case like though may I ask?
you have intake and exhaust fans?

What is your ambeint case temp like?

I'll have to go find some things for you to read about it grim, but I dont have a source for that right off the top of my head. I do have a bit of experience with it however, and its always been true for me. This is actually something I learned here on OCN back when I joined.

My old 2600 barton idled at 50c in windows, and would load at about 64c, but in BIOS it would read about 56-58c. Now on my 4600+ brisbane, I idle in the mid to low 20's (23-25c) and load at around 43-45c yet my BIOS always reads about 38c.

I have no idea why BIOS is a 80% load, I'll start looking for info for you (or some far more knowledgeable member here will tell us), but I've seen it enough times on enough different rigs, to firmly believe it that statement, but no offense taken, I'm naturally cautious of things I dont understand too. But if his idle temps are really 62c like you say... then for SURE his temps are all messed up (we can agree on that). In fact, you figure that with stock cooling, temps usually jump about 25c under load, that would put him at almost 90c! And I'm pretty sure that the CPU would either fry on the spot (especially after 7 hrs of orthos), or would trigger the safety shutdown if that were the case.

Anyway, the problem still stands, what is your ambient temp, that could deffinately be part of the problem?

Thanks for the response guys. These temps are all taken with the side of my case off and a large (2 foot) box fan blowing into it. The ambient temp would def be on the high side cuz the air conditioning is terrible in my room. I'd say close to 80F ambient. I do have an intake fan (90mm i believe) and the exhaust would be the power supply fan (about 120mm). The case I have is on the smaller side. It is actually very small. Air circulation doesn't seem to be a problem however even when the side of the case is on.

Grim, if you think it is a seating problem (which I also think could be a possibility) what would be the best way of going about ruling this out (without draining my bank account on AS5)? I mean if u put a bead of AS5 on the center of the cpu then set the cooler in place and then immediately remove the cooler, if the bead of AS5 spread out flat like a pancake wouldn't that tell me it is seated fine?

You might want to read through this review, where they tested a multitude of different ways to apply TIM. Its a good read.

http://benchmarkreviews.com/index.ph...1&limitstart=4

Sounds like your ambient temps could be a factor, and also you might see some improvement in temps from some better case cooling. Because only 1 intake and one exhaust is on the low side for a case, especally when overclocking. I would suggest adding at least another exhaust fan (perhaps a blow hole), and that should help out some.

Oh and grim, I've been looking around for you, and I still can't find any "hard" info on the BIOS loading. I've seen countless numbers of threads about it though, and most of the conversations are kinda like ours. The general consensus is that BIOS somehow (no one seems to know how... there are some guesses, ranging from needing to load up the drives, to a "static load" that is somehow generated) loads the CPU to around a 60-80%. I have messaged some of the well known members and mods about it, and have gotten the same response. So bottom line... BIOS loads your CPU to somewhere around 60-80%, but noone seems to have any idea why.

anyway,

Good luck with the reseating, let us know how it goes.

I still have yet to reseat the cooler but man does it make a lot of sense to see my temps drop 5C overnight when running an orthos test. I had my windows open in my room and the ambient prob dropped about 7F.
Anyway, I just wanted to add something I noticed. Not sure if its a big deal or not but when I was looking at speedfan I noticed the measured voltage for -12V was only about -7V.

Unfortunately, if your 12v rail is only putting out 7v, thats a pretty big problem. Its not supposed to go more than about 5-10% either direction (so 10.8-13.2v), and even then, it should be closer than that.

In fact, I don't even know if your computer should be running at that low of voltage (maybe someone else with more knowledge about PSU's will tell us). But I do know that power fluctuations can cause some bigtime stability issues, and can damage components if it gets bad.

Try checking it with another software (HWmonitor or something like that) and see if its reporting the same thing.

Oh and its nice to see that part of your temp problem is your ambients. A 5c drop is nothing to sneeze at. good job.

well, good luck

The +12V rail was ok it was just the -12V rail that was way off.

I don't think that CPU OC's that well. So I would just go for a Xigmatek. It is a great value for the price, and it should cool your CPU much better than your stock HSF.

If you continue to have problems by the end of August when school starts, let me know! I live by University Terrace

We are... Penn State!

Thanks for that PeaceMaker. Xigmatek is getting some decent reviews on newegg. Good price too. I'm thinking about getting one.. just hope it fits. I'll let you know if I'm still having trouble this coming semester. I'll be living near nittany bev..

Go for it. It is a pretty good cooler, I used it for my cousin's PC.
