High Cpu temperature with cabinet side panel installed

[Hardik9719]

ryzen 5 3600 - turbo boost off- 3.6ghz max

rtx 2060 

16gb ram 2400mhz

 

my cpu cabinet has 6 fans . 3 intakes in the front , 1 exhaust at the back and 2 exhausts at the top.

the cpu temperature while playing games is around 80-83c with 80% cpu usage.

gpu temp is 60-65c . but when i remove my side panel, cpu temperature drops to 67c, even at 100% load it hovers at around 72-73c . why is this happening? 13 degrees difference is huge imo. 

earlier i was using i5 6500 and temps never went above 64-65c at 100% usage.

Swap those two top fan as intake and keep the single back exhaust fan.

Was the old cooler also a top down blower?

yes , intel stock cooler.

That's not by any means bad.

i already have 3 intake fans in the front , installed as intakes.

Big gpu.  It’s going to be making more watts than the cpu.

I would try doing top intake as well. You're getting a lot of heat off of the GPU and it's being pulled up to the CPU by the exhaust. At least try flipping the front top to intake and leave the back too as exhaust as a test.

 

You've got enough exhaust with one rear and the empty PCI slots will vent any positive pressure.

One other thing. Try OCing and undervolting your CPU. Auto voltage is always really high and brings unnecessary heat.

Someone mentioned moving an exaust fan to the bottom.  Might have been a different thread.  I’m noticing the case has perforations being covered by the PSU.  I wonder if flopping the PSU so it draws from the case might do any good?  Kinda unlikely with modern PSUs.

I wouldn't bother with the PSU. Let it get cool outside air. Most PSUs barely run their fan anyway.

Yah.  It’s low probability.

Definitely recommend OCing. I run cooler at 4.2ghz all core at 1.25vcore than I do at stock with my 3600. I can run 1.1V at 3.6ghz all core.

That’s highly unusual.  Not impossible though apparently.  Are you overclocking while undervolting?  Undervolting would do it.

Reported voltage while under all core load is 1.35-1.4 with all stock/auto settings. Clocks are right about 4ghz.

 

My daily use OC is 1.352V (in bios) with medium LLC and 4.4ghz all core. Its stable in everything except prime95. Blender, cinebench and gaming etc are all fine.

 

I'm cooler than stock/auto settings at 4.2ghz all core at 1.25V and I'm prime95 stable. This runs almost exactly the same temps as stock mentioned above in prime95, but actually runs cooler during normal use/gaming.

 

I've never used offsets for voltage, only set vcore.

So undervolting.

You're creating positive air pressure, so you'd only have one exhaust out the back.
