I am looking for anyone else on this forum who might have an FX-62 or similar processor. I am curious as to what your idle and load temps are. I have been fighting with this thing for two months now and I cannot for the life of me figure out why it idles at about 50 degrees C. I bought an aftermarket cooler which seemed to help at first but didn't. I have reseated the processor and reapplied thermal paste TWICE (the first time i put a dot in the center, the second time i tried coating the whole thing with a credit card.)
No matter what I do it still idles at 50. I'm starting to think that the temp sensor might be bad... Has anyone else had this issue, or does anyone else have any suggestions? I can't even begin to overclock this thing until I get this under control... but this is very aggravating. If I don't keep my case fans on high it gets close to 60... and my fans are very loud on high... and since I'm in a dorm room and we use it to watch movies and such, it would be nice to have it as quiet and cool as possible.

This is the cooler that's on it now:

No offence, but Idle temp means NOTHING.

Your load temp is all-important, however i wouldn't recommend pushing it past 55° under load, which i'm sure your braking.

Whats the ambeint temp in your room?

Yea, I have been breaking 55, no other choice at this point.( I believe its rated at 60 max, but I've seen it hit 63... which scares the *&$% out of me, lol.)

The room temp VERY hard to pinpoint, lol. It's a dorm room that faces the sun. Usually somewhere in the 70's tho. I am on the window side of the room, but the computer itself is never in direct sunlight. You can assume it never is pulling air hotter than 80 (and I doubt that hot.) Thing is, even if the room is 65 or 80, I haven't been able to notice much of a trend. SOMETIMES the processor will idle at 44... sometimes 50 - USUALLY 50, but room temp doesn't seem to affect it too much. Admittedly, this is the first time I've spread my own goop on a chip. I used to just use the stock thermal pad and heat-sink with slower processors. I MIGHT just be doing it wrong, but I really don't think it's me, it was evenly spread over the whole chip and you could just barely read the lettering through it. Also it was just as hot with the stock AMD cooler, which in and of itself was a pretty impressive unit, and I did use the stock pad on that.

That's fairly toasty. I have the same cooler and I know it's one of the better ones. Possibly the chip is just a hot one... what's the TDP on a FX-62?

125w, but frankly the stock cooler will keep it cool - i've run an over-volted 4000 single core (admitly a single not a dual) at 2.8 GHz, and that was kept cool by the stock cooler (...just - loaded at 55)

Maybe you can lap your CPU? You can get a 10C decrease in idle temperature. And 6 to 8 full load.

1.) Yes, I can tell you that the stock cooler would have been MORE than sufficient. If you've ever seen the cooler that comes with the FX series its got 4 big copper heatpipes - its pretty cool. However, the base - for whatever reason - was horribly finished. It had little specs of tin or aluminum or something embedded in the copper... it was just yuck.

2.) About that lapping. Even if it did help, that wouldn't really solve my problem. I really want to know why it's running so hot to begin with. Even if I were to get a 5 degree drop under load, that's still over 55 degrees, which is too hot.

I'm about out of ideas at this point. I kind of want to contact AMD. Thing is, what kind of tech support do you get with a processor:

Support: So, are you SURE you seated it correctly?
Me: Yea, pretty sure.
Support: Well, are you SURE you gooped it correctly?
Me: Yea, pretty sure.
Support: Alright, well then it must definitely be a defect. We'll send you out a replacement right away.

Somehow, I don't see it working like that.

It could be the IHS of your cpu...

The problem is that there is no cpu perfectly flat. Some cpu are less finished then others. Even it's the same type or brand.

I also recommend using Arctic Silver 5 thermal paste

I am using the AS 5 paste. I even bought the AS 5 cleaning kit just to be SUPER SURE everything was done right, lol.

If your IHS is Concave/Convex it should cause an issue, but theres no point voiding your warranty on a chip you aren't even overclocking.

TBH i doubt they'll swap a CPU because it's running a little hot because it could be a faulty sensor, a dodgy application (what are you using to read the temp, btw?) etc, they're more likely to take it back if it dies.

Remember that i think you void the warranty by using a new cooler/thermal paste, but they have no way of knowing if you clean it (at least i'm sure they could tell but it wouldn't be cost effective).

If swapping coolers didn't work, neither did using AS5 i've got two suggestions - try a different temperature monitor (ie Everst, CoreTemp or SpeedFan) and check the BIOS (BIOS temp is idle though), and if they all give you the same odd reading then it's either a borked sensor (unlikely on such a good mobo), or the CPU is massively concave/convex (which i haven't heard of much in AMD systems) - if that, you can either fix it by lapping (...or removing the IHS), but your best bet would be to drop the people you bought it off a line and see if you can get a new one (unlikely) and then just live with having a hot chip.

I've tried AI Booster, Asus Probe and the BIOS and they all show the same result.

It was bought off of Newegg, so I dunno what they'd do to replace it. It's been a few months.

I'm going to ask my friend to re-seat and re-goop it. It it still runs hot after that, then it's not human error. It that's the case then I'm gonna be really, REALLY pissed off that I spent $200 on a defective processor. That's where my dad comes in. He's really good at getting people to replace things that aren't under warranty. Give him the phone and within 5 minutes he's talking with the company president and getting them to send us something new, lol.

Interesting find. Downloaded CoreTemp which looks at the temp readings from the on-die sensors.

Asus Probe reading: 48-50

CoreTemp reading (Core 1): 43-45
CoreTemp reading (Core 2): 40-42

Those temps were at idle, not load... still tho - the difference is interesting

Core Temp was always lower than PC Probe on my 4800+.

Stupid But -> Have you verified that the Fan is indeed running?

Speed Set -> You might have screwed up the speed fan settings on either the Asus PC Probe (return to defaults?), the Mobo, or even the Zalman if you use the manual setter.

Not much fun with a Hot CPU.

Good Luck

Is your case well ventilated? I had heat problems until I stuck 2 fans inside my case, one for air intake, the other for exhaust. It works beautifully, all my temps have gone down by at least 5 degrees, some even went down by as much as 15.

1.) Fan is running
2.) Fans are all set properly (checked AI Booster - all fans set to 100%)
3.) I've got 4 case fans. 2 120 mm (one in, one out) and 2 80 mm (one in one out). The case is a Lian-Li PC-60B Plus. I replaced all the fans, but I have not changed which way they blow, so theoretically I have the best airflow I can get. These are the fans I have:
