How can I improve airflow/ GPU temps for my case?

[TRazerK]

Here's an image of my current setup...



Case: Antec P8 with full tempered glass side panel
GPU: MSI GTX 1070 Gaming X 8G (non-OC'd)
CPU: i7 8700k with Cryorig H7 Quad Lumi cooler (non-OC'd)

Problem: I bought this case a few months ago when it wasn't as hot as it is nowadays. The case comes with 3 120mm Antec fans which have very low RPM (Max around 800 RPM only). You can see I have 2 of these fans fitted as exhaust in rear and top of the case. And for intake, I have 2 Thermaltake Luna 120mm 1200 RPM fans fitted at the front of the case. With this fan setup, my GPU temps are around 46-49 C on idle which is acceptable. But during full load, temps reach upto 77-78 C eventually after 20-30 mins of Heaven benchmark/ heavy gaming. Mojar bepar holo, when I take the tempered-glass side panel off and run full load, max temp is only 71-72 C.

These are just the temps I am getting nowadays. During the winter, everything was obviously 5-6 degrees lower so I didn't worry much that time. So, I now obviously realize that I have bad airflow going on inside my case

Question is, how do I resolve this issue? Do I...

A) Change the front intake fans to higher RPM/ CFM fans like CM Jetflo/ Sickleflow / whichever you may suggest ?

B) Get higher RPM exhaust fans ?

C) Change all of the fans ?


Sidenote: When on full GPU load, I notice that the hottest place in the case is right beside the GPU where the hot air is just getting trapped between the card and the glass panel. So that bit of hot air needs to be pushed out of the case, and for that I might just need better front intake fans? Please suggest if otherwise

Another sidenote: Yes, I do run a rather agressive fan curve on the GPU as shown below. Anything more aggressive than this does not help much with the temps, and is just too loud



Yet another sidenote: No problem with the CPU temps if anyone's wondering. Stays between 60 to low/mid 70s C while running CPU-heavy games/ Intel XTU, and between low-mid 40s on idle

Maintain an equal balance of inlet and outlet airflow. Though i prefer a bit more outlet.

TT fans are bullshit nowadays. I miss the good old thunderblades.

Buy CM Sickleflow as much as you can.

Yup- that's what I thought. These TT fans aren't doing any good. And the lowly stock Antec ones are even worse

So Sickleflow it is then- 2 in front and 1 or 2 as rear/top exhaust. Let's see how that goes. Will report back on Friday when I can get them

2 front, 1 rear and 2 up exhaust. You will be surprised to see the result.

So you prefer the dark (negative pressure) side! Most people complain about all the dust getting in that way. But the way I see it, amar case er vitor dust emnitey ekhono dhuktese, and I have to dust off once or twice every month anyways. It's unavoidable

From cooling perspective, positive or negative pressure doesn't matter as long as the ambient air in your room is cool enough. However, dust do make run things a bit hotter inside the case, you can try fitting lab hair net (as found in medical dispensaries) in between the fan/dust filter and casing wall so dust intake can be minimized without obstructing air flow (I do it even with dust filters included in my casing and now I need to clear dust only once in 3 months or so).

If you don't have AC running in your room then you must consider the dust and fan set up in your PC casing. And chances are your CPU cooler is not getting cool ambient air temp as the air is pre-heated from the case inside leaving your CPU temp at higher than usual and also leaving the case with hot exhaust air from your CPU cooling unit. All in all, you need to let more (Cool) air in your case to nullify the air intake of your CPU Cooler.

In your scenario, try this set up:
Front = In
Bottom = In (PSU)
Sides = In
Rear = Out
Top = Out

See if it helps in about week.

The amount of dust is very different though. I tried 2 intakes instead of exhaust on my side panel, temps did go down but within a month the dust build was more than what I'd normally get 3 months later. I bought dust filters too, didn't seem to help much.

I don't have any option to add fans on the sides- but I guess you meant it as a general scenario. Using lab hairnet as an additional dust filter is a very interesting take. I'll be trying that once I can get hold of them

As I said, dust is unavoidable no matter what the config/case fan setup. Even many tech reviewers have simply given up on trying to avoid it

So I did it. Went to BinaryLogic @IDB and bought 5 CM Sickleflow X fans for 600/= each. Put 2 in the front as intake, 3 in the back as exhaust. And wowwww. After an hour running Heaven benchmark 1440p extreme preset, GPU temps stay around 69-71C!! That's the same result I got while keeping the side panel open on my previous fan setup. GPU idle temps have improved also- 41-42C now on idle where it used to be around 47-48C before. Even CPU idle temps have dropped: 37-40C now vs 41-45C before. So I gotta say that mission has been a success!

Only obvious downside now is that the noise levels, which I totally anticipated from reviews. My rig is literally a mini jet engine now Soundmeter app on phone reports between 45-52 dB when phone is placed right next to the case. Not too bothered by it as I always use headphones, and also I'm a deep sleeper no matter what the sound level is

Many thanks to @VANGUARD and @Billybuoy for helping me out bigtime!

Get a fan controller or sth. Personally I just take out the molex connector while not gaming. I can't even stand the two fans and you have five. lol

Yup, I was just googling thru case fan controllers + trying out SpeedFan to control the 2 fans in rear/top which are the only ones I have connected to MB PWM. I believe fan controllers can't be found anywhere in Dhaka, so have to get one from Amazon. I'm still trying to figure out if something like this would suffice: amazon link. Can't seem to find any reviews for it, but one of the other ones that has 4-pin headers has some good reviews

Or does anyone know where I can get one in Dhaka?

[Billybuoy]

It's not very common in BD markets, most of the cases which have fan controllers built in so it is not available in cheaper price.

Here is an expensive one from Corsair sold by PC world Rajshahi:

It controls both the RGB lights and fans (three or four pins) by the way..

I found this on Amazon: https://www.amazon.com/Phanteks-PWM-...anteks+fan+hub

Much cheaper, and does the job of controlling the fans. Just need to find out if I can order it thru Backpack

Piggybacking on the tread.

My i5 8400 comes with a crappy stock cpu cooler and temperature reaches 100C when i run prime95 (thermal throttling kicks in).
So i have decided to buy a cpu cooler. I will proabably go with Cryorig h7. (the cm hyper evo 212 wont fit my case Antec GX505).

I will also buy some 120mm pwm case fans (non-led). Which one should i buy?

i have these two in mind:
ARCTIC F12 PWM : link

COOLER MASTER JETFLO : link


I want to install the new fans like this: 1 rear + 1 top + 1 front
I will install 2 of my stock fans like this: 1 top + 1 front (these are low rpm fans that runs at 950 rpm)

Get the Cryorig H7 Quad Lumi if you can. The cooler is quite upgraded from its predecessor H7, with 1 extra heatpipe. As for case fan, the JetFlo would be the obvious better choose. Much better airflow than the Arctic F12, but they're gonna be pretty loud so watch out for that

¤¤¤¤. I am definitely not buying the jetflo. It leaks and its loud:

So, my only option is between arctic f12 and sickleflow x? (the sickleflow x is quite loud as well)

Are there no other decent low cost case fans available in BD?

I'm using TT Riing 12 as case fan. Quiet and I just love the riing led. Doesnt move a ton of air like Jetflo but it gets the job done atleast for me. U can also look into CM Masterfan Lite which is cheaper.

wth!! even case fans leak?? :/ Thank God I didn't go for the JetFlo. They didn't have any at BinaryLogic anyways

yep but kinda rare though
