[SOLVED] Running PC for 24 hours without any case fan

[Exploding PSU]

Greetings..

First of all I apologize if I posted this on the wrong section, I'm still new here...

I'll try to make this quick.. I'm in the process of replacing my old case fans inside my PC (which by the way, I asked one thing or two about it here some time ago, very helpful).. The PC had 3 of those fans and it took around half an hour to remove them (the screws were problematic). The new case fans I've ordered haven't arrived yet, so the PC is now sitting without any case fans (no big deal, I had no plans on using it anyway)..

But then, all of a sudden, I got this important 'job', and I need to download a large file from the internet, a 100 GB archive worth of files and whatnot. I calculated the time it would take to download the file, it would take around 23-hours-something to download the file (let's just round it up to full 24 hours). I only have that fanless PC that I can use to download the file, I have no other options.

The plan is, I'll just go ahead and turn on that PC, and download that file. But I'm worried though.. Is it safe to run the PC that long without any case fans?
The PC will do nothing but download the file in the background, so I guess the CPU won't be used much and won't go hot (the CPU still has its heatsink fans attached, and it functions properly no problem).

So, what do you say? Running a PC for 24 hours without case fans, do or don't?

What's stopping you from reinstalling the uninstalled fans and have it running until the job is over? More stress relief than having to assume it'll be fine. I say assume since you've posted your question in a system's thread yet there are no specs to see.

Might it be possible to list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

You could pop the side panel and use a box fan or other household fan for the short term. Most modern systems run fairly cool, but in a poorly ventilated case you might run into problems. Downloading a large file like that shouldn't be much of a load on the system.

Thanks for the reply... The problem is idiot me already trashed the old fans.. As in, the trash can, outside.. All of the old fans mounting holes were mostly ruined because I had to pull them forcefully (again, screw problems), so I was like "alright I'll have no use of these anyway" and they headed to the trash can immediately. I admit I was careless at that part, but there's no way for me to get them back.

The PC is a run-of-the-mill standard office-spec PC, not a fire-breathing pixel-pushing machine. CPU is a Ryzen 3 1200, 8 GB RAM, an unbranded chassis, Windows 10 Home, 500 W PSU, ASRock A320M motherboard, and a GTX 970 used solely for display output... PC never go over 60 degrees celcius (140 F) for its lifetime.

I agree with Grimfox's suggestion that your best bet would be to at least leave the side panel off. It might be good to have a household fan directed at it just to be safe in case some non-actively cooled component doesn't have good air circulation around it, though with the panel removed, I suspect that the CPU and GPU fans combined with convection of the warmed air would be enough to keep the air circulating reasonably well.

Sorry for the late reply.. Had some things to do..

Yeah, I ended up following Grimfox's idea, I opened the side panel, and used my portable fan to cool it.. It seems to work really well though, I hope there'll be no problem later. About 18 hours to go..
