Hi, my name is Ola and I'm new in BOINIC project. I'm sorry for language mistakes, English isn't my first language.
I've got a problem with temperature of graphic card. When I touch ventilation slots on the graphic card's side after longer work of this project, they are realy hot. It isn't overheat but I'm affraid, that it may damage my laptop after a long time (my computer isn't new and I'd like to use it for 4-5 years so I need to take care of it). In bookmarks there is no option to reduce usage of GPU. Is it possible to "cheat" it and make my graphic card less loaded? I wouldn't like to resign from GPUgrid participation.

There are fancy tools like the "Nvidia Inspector" or the "MSI Afterburner" with which you can control the GPU clock (as well as the memory clock), thus controlling the heat.
Both for free download.

I guess you have at least a tool runnings which controls the CPU heat? This would also be important.

And yes, particularly with a notebook it makes sense to be cautious what concerns the temperatures (of the CPU as well as of the GPU).

Thank you for suggestion but this tool can't control usage of GPU. I've scared a bit because it works with maximum clocking! Do you know how can I reduce or limit it?

Pardon me for jumping in...

absolutely! +1

But I would even say that Notebooks are not really the best option for crunching as both the CPU and GPU sometimes sit on the same single heatpipe making things worse and the (single) fan working at full throttle.

There are fancy tools like the "Nvidia Inspector" or the "MSI Afterburner" with which you can control the GPU clock


yes... you can limit the temperature and downclock your GPU with MSI Afterburner, however the safe working range is still a narrow one and thermal stress hardly to avoid. Frankly I would advise you against using your notebook for crunching. Just my two Cents.

Thank you :) I've just reduced cklocking of GPU and graphic memory card. Unfortunatelly I can't limit loading of graphic card, the temperature is on the same level (62 Celsius degrees), too. When GPUgrid runs, the usage of graphic card is over 70%. Can it damage my computer?
JoerdF, my laptop has two fans at both sides, one for CPU and one for graphic card. But thank for your suggestion :)

@Ola:
can you reduce GPU clocking even further, so that the temp goes below 60°C ?

What concerns the GPU load itself, I don't think that you can influence this by any tool.
When you say that the load is over 70%, then by luck one of the less GPU demanding task is being chrunched at this moment.
There are others for which the load goes up to slightly below 100%, and this makes the GPU really hot.

At the bottom line, I agree to JoergF's opinion that a notebook is not really ideal for GPU crunching. It may work for a while, but "wear and tear" is very heavy, thus shortening the lifetime of the components considerabely.

I use laptops for crunching for years and only problem I had was damaged fan (1 bearing was noisy).
Ola - I didn't find information if You use cooling pad. If You don't use it - start.
Now I have 1 laptop that crunch with CPU only so it's only raised a 2cm over desk.
Other laptop crunch with CPU and GPU (only 1 heatpipe and 1 fan): it has https://www.arctic.ac/eu_en/arctic-nc.html that cooler under.
Additionaly in MSI afterburner I reduced "power limit" as much as it was possible. That keeps GPU at lower frequency and voltage.

The program TTHROTTLE can automatically reduces load on both GPU and CPU. I have been using it on all my desktop system. It also worked on my surface pro but I no longer use boinc as the Intel GPU on my pro 4 was supported by only a few projects. Plus I had no interest in eventually opening it up to replace its only moving part when the bearing wears out.

Thank you all, TThrottle really works :) Unfortunatelly the application crashed a bit and I can't open its interface again and correct my preferences (they're good but not perfect) but it works. Reinstallation did't help. I need to wait for the update. The most important is, my computer began quitet and cold.
@Erich56 My laptop is exactly mobile workstation so it has been created to hard work. Of course, I musn't exaggerate :)
@tito No, I haven't a cooling pad but I think about this. It may be very useful in the near future.
Thanks again, have a nice day! :)
