Case fans spin fast while downloading games

[Beefsteak Tomato]

CPU usage is at 30% is at a cooler temperature than in a demanding game and CPU fan doesn't spin faster, while my case fans spins up really fast and loud. Why does it do this? Does anyone know how to prevent this?

it could be your antivirus scanning files, whenever I download anything my windows defender starts using more cpu. Really the only way to fix this would be to by slower or quieter fans for your computer. or if you use something like Geforce Experience, you could see if you could slow fan speeds in performance settings, i wouldnt reccomend it though, a cooled computer is good

I might , but sense you dont mention im on laptop or i think its that, you need a older desktop pc to cause same issue.

your problem look like things like im in Balance mode, this means power reductions to system that then use more time on a job so it generated more heat over time.

laptop is know for throttle cpu cycle, and sense you might not work with machine or know just becuase things is on dont remove idle teampature on them, this is same run thing on low power still build up heat, to run full power faster and get job done can reduce heat.

other part of this is older pc with dust issue.

ps.
system is cpu harddisk and those 2 ( sense this is not GPU related not playing game same time that can cause even more heat )

so technically its work as intended , increase fans speed then you make more heat and dont have full power and have script that drag system down so save power look good on papir, fact is the other way, have a machine not run at was it was build for. ( this dont ruleout fans spin up but should calculated faster and that way reduce need for fan speed spin up, ( again wont work if cpu need to run at 100% just like i do in cancer research.

as i said you can learn alot on 100% cpu workload , know that system can handle it and cool enough doing and ( old days term was a system burn test ( bad word for just use a pc as test it was build for handle its performance and still work after several hours in it 24hour test even. )

reason i explan all this, sense you complain over own fans. that kickin then needed,
this still assume nothing is wrong other then you did not know such.

and you dont need explanation in steam use cpu and disk while install a game.
plenty of post do that.

The thing to check is your Task Manger under windows. See if any of the system resources are being hit hard andas long as the temperatures are OK don't wory about it.

It's normal for a high number of resources to be hit as Steam downloads games encrypted and compressed. This means when you download it isn't a case of your net connection streaming to disk and that's it.

It requires your I/O, hard drive, RAM, CPU and much more all to work as the games need to download a chunk, unecrypt, swap the data around and then write it to it's final place on drive, then carry onto the next chunk.

If you have an Xbox One or PS4 you can similarly see it beahve a bit like this too. If you start up a 360 game on an Xbox One the fans will often go wild for a few seconds.

Because your computer is heating up from the process and is spinning up the fans in an attempt to control its temperature. You don't prevent that.

Depending on your mainboard you can set some fan curves to adjust your fan speeds in certain load scenarios. This is mostly done in the BIOS, but there's also some software to do it.

But my temps are higher when running crysis and it doesn't make that much noise then so it's not a heat reason

Ah but do understand that your PC knows what it's doing.

Some games will run hotter but as longas the termperatures are being managed, the fans won't spin up too fast. It's when there's a sudden increase in demand that needs them to ramp up.

So only deal with fan profiles when you REALLY know what you're doing and you have data that is demonstrably better than what the manufacturers have set.
