hi guys,

the weather have been very warm over here in Cornwall and just wondered if anyone of of you have your fans at max for safety? right now i have set my fans all at max, 4 case fans and cpu fans. its not overly loud but you can notice it though. also on my new psu, there is a fanless mode, i was thinking about pressing the button so the fans stays on even at low load.

what do you guys think?

just want to look after the new build is all

my full specs:

Mainboard: ASRock b560 Steel Legends ATX
Processor: Intel i5 11500
Memory: Crucial Ballistix 3600Mhz 16GB (2x8GB) RGB Gaming Memory Black
Power: Seasonic Focus GX-650 650W 80+ Gold Modular
Case: phanteks enthoo pro m
Hard Disk: Seagate 1TB
ssd: 256gb
hard disk: 2tb

this is my current temp:



to be honest, everything seems the same, only difference i have noticed is the airflow gone down by 2 degree. when at standard mode( not the cpu fan) airflow was at 40 c but with full fans, airflow is 38 c.

many thanks

the 38°C "Air Flow" indicator shown is the temperature of your 840 EVO SSD.
while 40°C is not ideal, it's not a dangerous temp or anything to really worry about.

never.
even with quieter fans in place i will always try to reduce their speed and with it their noise as much as possible.

you should create your own custom fan curve profiles for separate sections of the system.
example:
1 for CPU cooler fan(s),
1 for front intakes,
1 for exhaust.
this way you can determine what the best speed vs noise vs temp setup is for the entire system.
a good starting place for figuring your individual fan curves is:
25% RPM @ 30°,
55% RPM @ 50°,
75% RPM @ 65°.

the ideal setup for that case with an air cooler on the CPU would be;
3x 120mm front intakes,
1x 140mm rear exhaust,
1x 120/140mm top-rear exhaust

goal for CPU temps should be:
~30°C while idling,
<\=60°C for max work load,
~70-75°C for heavy stress testing.
on my new psu, there is a fanless mode, i was thinking about pressing the button so the fans stays on even at low load.
why?

if your PSU is installed correctly,
with it's intake fan facing down towards the vent in the bottom of the case,
than it's temperature should have nothing to do with the rest of the system.

it is isolated from the other components and is pulling in it's own cool air from underneath and exhausting it's own heat out it's rear vent.

many thanks, will try set a fan curve for each fan.

yes, my cpu is at 30 while idling so that is good.

in manual for psu, they said to make sure the fans face inside my pc case, that is what i have done. should i change it back?

that is only for cheaper cases that don't have a PSU intake vent.
yes, you should have it with the fan facing down.
this way it can pull in it's own cool air instead of the warmer air from inside the case.
many thanks again

have changed it back with the fan facing downwards. the fans has not been on at all yet. dont think i have been stressing the pc too much.
