CM nepton 240m issue!

[Acidust]

hello,

 

Well some time ago i bought the coolermaster nepton 240m and after 2 months of use the pump died so i send it back to get a replacement and today it arrived!!

 

After i installed it for some reason the pc wont boot !!! It does power on and everything is working pump lights , pc fans , mobo everything looks ok but there is no singal going on the monitor.

I tried reinstalling the stock cooler to see if there was another issue with the computer but with the stock cooler the pc is booting fine!!

 

Is there a chance this unite is also dead cause it looks like its working!!

 

Mobo:asus maximus vii hero

Cpu:intel i7 4790k

I don't know if this is possible but try using the stock heatsink and plug in the 240m at the sametime with it being on a desk not on the cpu see if it boots.

usually the 8-pin will get dislodged or disconnected (can't see it). verify

the 8-pin.
