Air Flow in PC CPU

[MevolutionX]

Take note though, each channel support 12W or 1A only... So dun overload each channel.

I only hooked one fan to each channel. Don't think I will overload it. fan controller is the way to go! Otherwise the sp120 @ 2350rpm will burst your eardrums.

I think some people are very sensitive to fan noises. I, personally, do not mind having that sound of air wizzling through the fans. The noises are actually caused by the air movement right? Because the fan motors are purely silent by itself.

Used to be okay with fan noises, ran my SP120 at full speed. Then I realized the noise to performance ratio is not worth it. The temps isn't that much of a big difference

My NZXT Phantom 410 comes with a built in fan controller with 3 speeds. And boy do I see the difference. Yes, 1°C may not seems much. But this 1°C can cause ice bergs to melt, thousands of deaths in the hotter regions, forests dying and the ecosystem diminishing.

And during a game if I turn the speeds up, I can see a few °C drop in my GPU temp.

Meaning, air flow is actually important. Lousier than water-cooled systems, but a convenient, easily customizable and flexible cooling method. Not to mention, cheap too.

Talking about airflow.
Let me share mine
Currently on nzxt p410

2 front Gentle typhoons pushing fan in the case.( with added front decmiflex filters)
1 bottom SP120 H-perf bottom pushing air in the case to feed gpu (added decmiflex filter)
1 back AF120 H-perf to pull air out of the case
H100i with 2 SP120L pulling air out of the case with rad at bottom and fans on top

With full fan speed on using the fan controller
With OC 1.235v, 4.5ghz max temps 81deg with no aircon (h100i fans spin at full)
Gpu stock settings bf4 gaming, max temp 73deg with no aircon

Not sure if it's good enough, haha but looks ok to me. To drop further, have to WC it

Are decmiflex expensive? I saw the thread and the pricing is quite high, if you add all the shipping, handling and customizing fees together.

not really. paid around 30+ sgd for 2 piece of the filter.

Dude, seriously. No need to drool over every single degree drop temps. Yes it's fairly important, but no need to be obsessed over it.

Everybody has their own interests. Some like LED-lit, flashy and cool cooling fans even though normal ones can do their jobs. Some like to customize their keyboard keycaps even though the stock ones can suffice?

You will have your own obsessions, but for me, I like to see fans performing when they are supposed to do, that is 'cooling'. I also like to customize the movement of the air inside my casing.
To each their own, No?

buy some dry ice to see the air flow pathway

agreed! when i used to play with hardware everyday (about 3 years ago) i would always be staring at my casing and fans, always hunting for great deals for fans in the marketplace and trying to optimise my airflow and cooling. i would always use tissue paper to test every fan's airflow and pressure..
i still run the same setup as 3 years ago (negative pressure, dust magnet) with the same old case but i am planning for a complete rig overhaul while reusing my good same old case, breathe a little life into this old casing.

If you need an extra helping hand you can pm me.

U dont want them to get too cold because condensation will cause disastrous harm to your parts.

Someone got my point! +1 +1

Precisely. The only reason I said that was because I was once in TS's position. Owned a P410...with additional aftermarket fan controller. Even made a thread asking around about the "best airflow config" for the P410. Well guess what?

Eventually one would reach the realisation that excellent temps are wholly subjected to SG's prevailing weather conditions (or whether the A/C is on if you're elite).

Each to their own, and I won't blame anyone for hunting down the last 0.5 degree in their CPU/GPU/HDD/SDD/PSU/chassis. Just one day, you'd find it silly and won't be bothered anymore.

to me the temp not crazy can liao

 

[DeenzX]

Some 3rd party applications will show your temp as crazy. The most accurate one for Motherboard is the bios.. but are there any other apps with accurate measurements? I used HWMonitor and the CPU temps went up to 104C which was insane.

 

[Phelan]

It is possible for the CPU temp to hit 105, if you're overclocking and using the stock cooler, or just did your installation wrongly.

Yes, if you overvolt them too much...

Undervolt your CPU at stock speed until it is stable first then OC from there. You can use stock cooler to go until around 4.2ghz without going above your stock voltage (assuming you got an average chip)... Any higher, please get a decent cooler.

You're doing something wrong for it to reach that high. Overvolted too much, cooler never mount properly, reaching limits of stock cooler etc.
