I have an old PC case with only a few air holes. about 10 small air holes at the front and 1 of 10 cm at the back. no more.
My configuration is :
- Intel I5 6500
- 3 disc drives (each of 7500 RPM)
- No PEG graphics card (use Intel I3 graphics card of CPU).
- motherboard : asus H81 plus (ATX).
The PC is much used (about 10 hours a day), it is about 19 degrees at the place of the PC.
I only have 2 coolers placed inside the PC case (one of the PSU and one for the CPU). That’s all about the coolers. At my motherboard (Asus H81 Plus) no coolers. There are 3 disc drives inside (3,5 inch disc drives of 7500 RPM sata 2). Can it damage my PC or do I have to place more coolers inside the PC Case ? Can it damage at the long term without coolers ?
I wouldn’t stress over it if it’s non-overclocked and within normal use ( not constant CPU intensive ). Asus has protections for it, so it’ll throttle down but stay safe. But if you want maximum performance really out of it… then single fan could be useful ( I’d assume southbridge gets bit more workout with CPU graphics too ). Even my 1st and only package built PC 386 had a case fan… so guess it’s there for a reason. I did run a slightly overclocked athlon XP ( one of the most heatproducing CPUs known to man ) for a decade in a fully enclosed soundproofed case with only one 120mm intake fan… it still runs ( haven’t used for 3yrs tho ). But try some MB temp sensing software… I think Asus had one or D/L one like HWinfo or speedfan etc. See if it gets over say 55c then it might be a prob.
