uxcell a15071500ux0720 PC Computer 50 mm Case Fan Dust Filter Guard Grill Protector Cover (Pack of 2)

so I put this nice cheap eBay computer together and running really well so far doing everything it wants to actually is probably better than my original gaming computer that I built the only issue that we found is that it seems to be running a little bit hot so I set up the hardware monitor on there it was a little bit warm running around 70 degrees Celsius again that's not very hot but I want to see if we could cool it down in order to cool it down what we ended up doing is just running it with an open case but I didn't really want it run open case if we could help that at all so I thought let's boot a ventilation fan in there but a ventilation fan that would fit in that kind of a slim form factor computer would be about a 16 millimeter fan maybe and that those run pretty loud so instead I decided you know what I'm just gonna cut a little hole in that case so I can blow mainly directly
