Bitcoin Forum

Hi all,

I've been reading throughout the forums and not sure where the smell comes from.
I've put together a PC with 2 x HIS 7970 and a Corsair 750CX, the rest is minimal a 500GB HD and an 3300 AMD cpu with 4GB Ram.

I've got air cooling and my settings in cgminer do not allow more than 75C which works fine.

Now, the system doesn't hang, it's stable and mining, however the room gets a bit smelly. The power is 510W at the wall so I guess Corsair can accommodate for the gpus needs.
I've got one fan at the front, one at the side for cool air, and one at the top to blow out the hot air.

I tested with another system, (bigger case) with a Q6600, 8gb ram and a few hard disks and only 1 of the two gpus, and a 650W Corsair. Still the same.

All the above is for Bitcoin mining, when it comes to LTC the spinning is faster obviously and the smell more intense.

Any suggestions?  ???

what kind of smell are you getting? Also is the corsair running hot?

I wouldn't say it's a burning smell, I would say it's seems more like "new stuff" smell. To be honest I haven't touched the psu to check if it's running hot, I've purchased it based on assumptions I found on the internet about being able to handle the load...

So what should I look for a) if it is hot, b) if it isn't hot

Thanks

PS Don't know if that says it all...

That really doesn't sound good. I'd take caution.

If it's not a burning kind of smell then there's nothing to worry about, just give it some time and this new-stuff smell will be gone.

Thanks for that. Again, it's not an unbearable smell, it's just a background annoying smell...

I'll open a new thread for psu suggestion.

While usually it's a new hardware smell it also could be your psu.

I had to run my 7950 for a limited time with a weak 350w psu.
While it was ok with lowered clocks, it burned out eventually, I'm glad I was home to shut it down.
Some 3-4 hours prior it was emitting smell which did not seem like burning nor new hardware smell.

I'd keep a watchful eye if I were you.

My 7970 just went up in smoke without warning.  Keep a close eye on it and figure out what is running hot.

Check the temperature

Get a laser thermometer, they are cheap nowdays and they work wonders for assesing the amount of heat a component produces.

all new pcs smells on beginning especially when is 60c and more....its normal...

agreed probably the lining on the GPU cards (they do discolour when run hot after a while) but also make sure the cables VGA DVI HDMI arnt getting hot from the exhaust of the GPU (melted the rubber of a vga cable this way which left a very very strange smell also, does it smell like a glue/paint if so its the GPUs settling in with the heat but just check every so often that the pretty stickers on the GPU casings are still there and not fallen into the GPU below

it's normal

Typically, new hardware has factory processing residue which will burn off at initial maximum heat exposure. If smell stays or gets worse then you have a overheating problem most likely.
Good luck.

Or just put your cold coffee cup on it, if it becomes hot coffee it's too hot.

RMA your PSU now and replace it.

I had a 750W PSU running 2x6870's for little over 12 hours before it literally went bang and sparks shot out of it. For those 12 hours it was a kinda "hot" smell, even though the PSU didn't feel hot. Faulty capacitors. Best be safe than sorry

Definately, I agree get a laser thermometer.. plus they are really cool to play with..

I'm running 1x7950 + 1x7970 on 700w psu. Your psu was deffinetly faulty cause one 6870 power consumption is about 150w

I agree with others saying it's normal. I've frequently had that problem with new PSUs and GPUs. It goes away. So far, I've never had anything burst in flames, burn up, or go bad (as far as PSUs and GPUs emitting a "plastic-y" smell). If you can identify the smell as coming most strongly from a connection point, then you probably have a problem. If worried, I'd check the connectors every few days -- just pull them all up, examine for any warping/melting, and plug them back in until the smell goes away.

5970 max temp 95Cº are OK

Hey try to look for any stamps on your motherboard or on your GPU's there are quite few on any new hardware, if you want any more help on this a picture or 2 on the hardware will be appreciated.

need a new computer

Hi made my 1st mining computer with a single Powercolor 7970 + Corsair CX600M + Bitfenix prodigy case.  I left it overnight, the room got to be about 29-30'C with AC off.  When I came back and opened the door to the room, it smelt like stinky feet.  And it seemed to come from the case.  Few days later.. all fine now, no more smell.  My cgminer target is 73'F, normal fans ranges about 50-65%.  The VRMs on the crappy powercolor 7970 are naked, so they are not nearly as cool as i'd like.  Wondering if its the corsair powersupply since we have the CX series in common.

Or hot ;)

Unfortunately, if the power supply is not of quality after little to do mining will ruin.....

my laptop reeboted after trying to mine yacoins , i would not tell you more...

Could be from the grease that is making the fan run smooth. Had that myself, a couple of weeks later fan completely stopped working and I had to buy a new from ebay.

Use google nose (http://www.google.com/landing/nose/) please so we can give you a more specific advice.

Thank you.

It is completely normal, that new thigns have a certain smell once they are heated.

Take a smell from your router, your TV. Take the smell from your computer exhausts from the PSU.

There is a certain "electronics" smell, that is completely normal.

If the PSU burns up (I destroyed a few with experiments when I was younger) the smell is different, it is more pungent and not as "sweet" from the smell. Also, the smell from destroying the capacitors in PSUs is quite intense.

If you have time to spent, a psu to burn, want to see this smell and won't sue me for whatever happens when you do this, put a psu in 110v mode when on a 220v electrical supply. If your house burns off, don't blame me, but the smell is what you smell when electronics "die." ;)

I would get someone to look at that my friend.

 ;)

That's the answer my friend, thanks. Btw PSU is warmish, I'd say normal temp. GPUs are burning hot!
