Thunderblade 120mm 4Pin Molex

[paulm_2008]

Hi, I recently purchased 4 120mm Thunderblade LED case fans. I was oping that as with other fans there would be an adaptor supplied which would allow me to connect these fans to the male 3 pin header connectors on the motherboard. However having received the product, I was somewhat dissapointed to find that not such interface device existed. Is there any way in which the 4 Pin Molex + seperate single wire [on a 3 pin female header] RPM sensor can be adapted to enable me to connect the fans directly to either the motherboard headers or a fan controller ? I must admit I think these fans have this configuration for a reason [i.e. current draw is probably too great to directly attach to the mobo]. Any Ideas/Help/Reccomendations would be more than greatfully received.

Regards

Paul

AKASA 4 pin to 3 pin fan converter cable would do the job, something like this

There's plenty of power available on the motherboard and I have several 120mm fans that have the 3 pin arrangement so that's not the issue. If you're hoping for a more DIY solution then something like this is a start

Googlage otherwise.

While that's a good adapter I think that it would only allow the OP to connect the fans to the mobo and get power...not be able to read or control RPM. I noted in the pic that there's only 2 wires coming off of the 3 pin connector...the RPM wire seems to be missing.

Hi, thank you for taking interest in my issue, as halcyon correctly states, this product although it would do the job would not allow me to monitor the RPM directly. I'm wondering If for example I could connect this product [linked above] to my fan controller and the single 3 pin header [RPM sensor] currently on my fan to the motherboard header, then use for example Probe II [ASUS] to monitor fan rpm and adjust the voltage via the fan controller - its a real mess but it probably would work. I cannot see why no single thing exists which would allow all three cables to be connected to a single female header block [this I cannot find]

The DIY option via the link below may be worth a try though

I will have to see where I can source these items in the UK

This may do the job, again I need a UK supplier !!!

Nope - only looks like power, no RPM on this as well....
