[SOLVED] Fan Detection

[BVleu]

Hello,

So I've noticed recently my temperatures in my computer being very high up to 95c while gaming. I'm using a prebuilt PC and when I first got the computer temps were not a problem and it's only been a recent thing. The PC is around 1 year old and I have not cleaned any of the fans since my purchase. The PC has a AIO cooler and then 3 fans 2 on the front and 1 at the top. I wanted to confirm that my AIO was not dead so just checking the fans in the default Asus software and HWMonitor I'm only displaying 3 fans. CPU Fan (The Top Fan), AIO Cooler at the back and 1 fan at the front, however, it is not showing the 2nd fan at the front. I'm wondering if this is because the fan at the front is already displaying so the RPM are synced and it doesn't need to display or should it display both of them?

I have also confirmed that both of the front fans are spinning up so I'm wondering why it doesn't display.

In regards to my temperatures should I clean the AIO fans? or do I have a deeper issue here possibly?


I should also say my room has a serve dust problem I do clean the top of the PC and the front but never have fully compressed air and cleaned any of the fans so this leads me to think its all dust related

Have you ever cleaned the PC?

Power the unit down and disconnect everything. Take off the main side panel into the equipment and check to see if there are any filters on the case. They are typically slide in or held with magnets and such.

Take the PC outside and blow it out with a blower, or canned air. I don't suggest using a compressor unless you know it has a water filter inline. Clean any filters in the sink. If there is a residue left after blowing the unit out you may have to take towels/wipes and clean off the fans and such. In extreme cases you may have to do some disassembly to reach everything.

Almost all fans generate a speed signal to send back to its host fan header. It consists of a series of pulses 5 V high, 2 pulses per revolution. The header counts these in a short fixed time slice to get the speed value. If you connect more than one fan to a header (using a Splitter or a Hub), you can NOT send back more than one fan's pulse train. Two or more sets of pulses never are synchronized, so the header would "see" wildly varying numbers of pulses per time slice, generating wild readings and possibly error messages. So any Splitter or Hub will send back to its host header the speed signal from ONE of its fans (the port that does this is marked), and ignore all the rest of its fans' speed signals. This has NO impact on ability to control fan speed - in fact, the header does NOT use that speed reading to control the fan speed. IF your fans are identical, you can just assume they all are doing nearly the same thing. However, the header DOES use the speed signal for a second important function - detecting fan FAILURE - no speed signal to count. But it cannot do that part for fans whose signals are NOT sent to it. So when you have a Splitter or Hub for fan groups, YOU should check from time to time to verify that all your fans still are working.
