Title: TB250 BTC pro - supporting multiple fans Post by: deskless on June 28, 2018, 07:24:11 PM I am trying to put 6 fans on the rig but I only see one pin on the motherboard to hookup fans. Any suggestions on what to do?
Title: Re: TB250 BTC pro - supporting multiple fans Post by: Elder III on June 28, 2018, 07:51:29 PM You can use either a molex to 3 pin adapter or you can get splitter cables that go from 1 to 2 or even 1 to 4 3 pin fan connectors. If your fans are molex models you may be able to daisy chain them together too.

Title: Re: TB250 BTC pro - supporting multiple fans Post by: deskless on June 28, 2018, 07:54:46 PM I am using this fan
https://www.amazon.com/ARCTIC-F12-PWM-PST-Technology/dp/B00NTUJTAK/ref=sr_1_3?ie=UTF8&qid=1530215608&sr=8-3&keywords=ARCTIC+F12+PWM+PST They provide a way to chain them together but my worry is that if I put 6 of them together , the first fan's wire will get overheated as it will carry current for all of them. Title: Re: TB250 BTC pro - supporting multiple fans Post by: Vann on June 28, 2018, 08:09:08 PM The Biostar TB250-BTC Pro has two 4-pin system fan headers. One next to the CPU fan header and another on the opposite side of the motherboard next to the 4-pin molex PCI-E aux power connector.
https://image.ibb.co/exLzZo/TB250_BTC_Pro_Fan_Headers.png You can use a sata to 4-pin PWM fan header splitter to connect multiple fans to the same header so they all run at the same speed set in the Bios. https://www.aliexpress.com/item/5-x-4-Pin-PWM-SATA-Power-Supply-Cable-Connector-45cm-Computer-Case-Fan-Cable-5/32838394261.html? You can also use a sata or molex adapter to power multiple fans but they will all run at full speed. https://www.aliexpress.com/item/Del-Molex-4-Pin-To-4-x-3-4-pin-5v12v-Usb-Sleeved-Dual-Fan-Power/32828730924.html? Another option is to use a box fan instead of a bunch of small fans. Cheaper, much more effective at removing the hot air around the rig and easy to replace. https://www.homedepot.com/p/Lasko-20-in-Power-Plus-Box-Fan-B20540/300202629 https://image.ibb.co/eHQSn8/Rigs_With_Fans.jpg Title: Re: TB250 BTC pro - supporting multiple fans Post by: deskless on June 28, 2018, 08:25:01 PM Thanks a lot for the explanation. My rig is on top of armoire and am still trying to find a box fan that can fit in the narrow space.
Title: Re: TB250 BTC pro - supporting multiple fans Post by: Elder III on June 28, 2018, 09:06:31 PM Yes, box fans can be a great option. We use them on more then half of our rigs and have been quite pleased with the results so far. They wind up being a cheaper option in most cases too.
