However I can't find anywhere online that says how many PWM fans I need or how I connect them all. Any info would be greatly appreciated. < > Сообщения 1–15 из 15 [☥] - CJ - Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:20 How many you need/can connect depends on the available PWM fan headers your motherboard has.PWM simply means being able to control the speed of the fan, either with a fan controller or via your motherboards fan settings in the BIOS.4pin headers are for PWM Отредактировано [☥] - CJ -; 26 дек. 2018 г. в 16:22 #1 Fuzzy Dunlop Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:22 PWM fans are connected to the motherboard fan headers or fan controller, you can use fan splitter cables to add more than 1 fan to each header. There are a few ways you can change your PWM settings such as "SpeedFan" etc which i find to be a piece of crap, best to just set your PWM fan settings within the bios.

They are not "better" a PWM fan is just as capable of cooling your PC as a DC fan. But PWM fans can be configured to spin slower and be much more quiet when the system is not under load. 1 fan in the back and 2 in the front is all you need in a gaming machine. Adding more is useless, they only create more noise and pull in more dust. PWM fans connect to the same headers the DC fans do. The only difference being that the DC fans will only use 3 out of the 4 pins on a PWM fan header and the PWM fan uses all of them. When swapping DC fans with PWM ones you do have to change a setting in the BIOS which tells the PC it's a PWM fan, otherwise it will be opperated like a DC one. Pretty much any modern motherboard should have PWM fan headers. I don't recall seeing anything modern with only a DC header, asides from in prebuilds with weird motherboards. #3 Killer_Bean420 Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:37

So my motherboard should have 3 PWM fan headers spare (as well as the CPU cooler connector)? Sorry if I'm being dumb I'm just not familiar with this side of PC hardware #4 Omega Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:43

I don't know. I don't know which motherboard you have. #5 Killer_Bean420 Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:47

I don't know. I don't know which motherboard you have.

I just googled the specs of my motherboard (Gigabyte GA-78LMT) and found this:1 x CPU fan header2 x system fan headers1 x power fan header1 x front panel headerWhat is the difference between all these? #6 Omega Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:51

Which board exactly? There are two different boards with this name,- Gigabyte GA-78LMT-USB3- Gigabyte GA-78LMT-S2PAnd a million revisions of both. #7 Killer_Bean420 Открыть профиль Показать все сообщения 26 дек. 2018 г. в 16:57

The USB3 one and I have no idea what revision it'd be #8 [☥] - CJ - Открыть профиль Показать все сообщения 26 дек. 2018 г. в 17:27 That board has 1 4pin CPU header, and 1 4pin other fan headerSo 2 PWM headers in total, 1 of which is the CPU.All revisions of that board have the same amount of fan headers.So you are down to the CPU fan, and possibly a front case fan as the header is closest to the front of the case, possibly a top mounted fan as well depending on the length of the cable. As far as PWM fans and the motherboard goes thats all you have access to.-PWM doesnt mean its better than a 3pin or molex powered fan, you just have more control over how fast the fan spins.

I was actually given 3 PWM fans for Christmas (2x 140mm for the the front and 1x 120mm for the rear) so what's my best option? #10 Killer_Bean420 Открыть профиль Показать все сообщения 27 дек. 2018 г. в 2:35 Best way to hook up 3 PWM fans to my PCI was given 3 PWM fans for Christmas but not sure on the best way to connect them all.

I don't have any adapter's currently.Case: Corsair Spec 03Fans: 2x Be Quiet Silent Wings 3 PWM 140mm1x Be Quiet Silent Wings 3 PWM 120mmI've heard that it is potentially dangerous to use splitters on the motherboard so would this mean buying a fan hub? #14 [☥] - CJ - Открыть профиль Показать все сообщения 27 дек. 2018 г. в 4:19 I know of no such issues in doing soBut if you're worried about it you could simply just get Molex to 3pin or 4pin fan adaptersAlso -Front: 2 x 120mm / 140mm (1 included)Top: 2 x 120mmRear: 1 x 120mm (1 included)Bottom: 1 x 120mmSo you have some options for that caseJust connect them the way they are currently connected Отредактировано [☥] - CJ -; 27 дек. 2018 г. в 4:21 #15 < > Сообщения 1–15 из 15 Показывать на странице: 1530 50 Все обсуждения > Форумы Steam > Hardware and Operating Systems > Подробности темы Дата создания: 26 дек. 2018 г. в 16:17Сообщений: 15 Новое обсуждение Правила обсуждений
