Bitcoin Forum

I knew that Bitcoin would increase my temps. My computer is semi-new and I haven't done much full load testing, but Bitcoin makes my machine rise 20-25 degrees C. It's still safe, at 57...but just curious. Do you all run Bitcoin 24/7, and if so, is it bad to run at 100% usage, at such a temp, whenever the computer is on? I've played games or used certain programs with high load for a while, but never thought it would be healthy to support higher temps non-stop.


Also, an idea while studying this earlier. It may be small potatoes at this point, but a scheduler to accomodate different times you want it to run and/or how many processors you want running at once.

For example, it would be nice to have it run on full load while I am busy or at work, while slowing down to one or two processors during my main usage hours. Or for those with a computer that is a bit old or they don't exactly trust, turn the load down at night or when you are not home for safety precautions of temps.

Like I said, a timer/scheduler like that is small potatoes, but at some point I'd really like to see it in the Options menu.

I have a Core2Quad Q9450 (4x 2,66 GHz).

My system went over 70°C with the original boxed intel cooler. This was far too high, so I installed my Thermalright IFX-14 and now my CPU cores do not go over 55°C.

So basically, yes, when my PC is running, Bitcoin is also.

Make sure that the bitcoin.exe process is not 'fighting' with another system process or 'live protection' engines. ( See my post in Technical Support > Win32 CPU Cycles vs 'Live Protection' Engines ? )

I guess also try setting your 'Limit coin generation to 1' in options, but that might be the same as the default settings ?

I'm running 24/7 on a dual core system using just one processor for Bitcoin, however I don't even hit 100% CPU usage when using both processors and I'm also running Grid Republic, Gomez Peer and MT4 at the same time ;D

Aside from any conflicting processes, check for the latest system drivers and upgrades, do a disk clean up and defrag. Try adding a Virtual RAM drive perhaps or increasing your Virtual Memory (paging file) on XP to a 'system managed size'  and set Processor Scheduling to 'Background services' ?

You could also defrag your paging file http://technet.microsoft.com/en-us/sysinternals/bb897426.aspx

Filehippo.com is a great free software resource for windows users. I recommend CCleaner, Defraggler and Speccy.

SpeedFan 4.40 is also free and maybe of use to you.

Bitcoin could really use a % usage setting though, similar to that of the Grid Republic software :)

It depends a lot on the cooling capacity of you computer. If your cooling is struggling to keep your core temperature down at 100% load then you're probably going to wear out your fans in the not-too-distant future. If your cooling system isn't breaking a sweat to keep your CPU cool then you probably won't have much issue with mechanical wear.


That's not a bad idea. It might just be a better idea to make the load scaling work better by automatically cutting down the number of hashing threads based on the amount of load other system processes are putting on the system. That way, if you weren't using the computer at all the client could suck up all of the cores, but if you sat down and started doing big parallel compiles then it would back off to 1 or 0 cores.

The way that load scaling currently works in client is slightly problematic, in that the 'niceness' of individual processes doesn't affect its IO demand. Since the current BitCoin client is such a monster when it comes to disk access, you'd probably notice a huge responsivity increase on your system if you ionice'd the client.

How do you measure the temp of your computer? I run it non-stop, but shut it down every 2-3 days to just cool it a bit. I am running an old dell machine and I am not too worried about it.

You can use Speedfan. It is a software to monitor fans speed, temperatures and voltages. You can change the fan speeds depending on the temperature. The system displays charts and an indicator in the sytem tray. You can configure it to execute an action based  on the sytem status. It is simple to install and use. You can search in google, i think this software is famous for what he does. No idea of any others but sure there is

i hav had my computer running for 3 years non stop :D im not worried.

many people (office workers, security guard stations, control rooms, home entertainment/smart homes) have their systems on 24/7

it used to be a big problem during the 'solo mining' days of bitcoin where mining bitcoin with your CPU would kill it.. but these days, there no real long term affect because we are no longer mining with out CPU any more

laptop or desktop ?
that is the question ...

I run a bitcoin core
- on Intel Core 2 Duo Processor E7500,
- on Intel Core i5-560M.

2010 processor for both ... no problem.
Bitcoin core take LESS than 20% of this CPUs.

if laptop. the only thing i worry about is the battery.

i have seen many batteries die within a year where the power cable is plugged in 24-7. usually best to unclip the battery and run on just the power cable 24-7 and just clip the battery in once a month-6months to top it up and reenergise it due to natural depletion of non use.
