It makes me headache. When a program or game uses Gtx870m, the machine makes the tick noise which is annoying.
Here is the video. Turn up the vol and listen.

Anyone has the same problem?

Ticking noise sounds like defect to me

Seconded. Either the fan is bottoming out on the case, causing drag, or something in the fan itself isn't sitting right, causing drag. I would contact Razer immediately. Would also send them the link so they can hear it for themselves.

Probably a buzzing or hitch pitch noise or a coil whine.

This also happens with my 2013 blade...It is most definitely not to do with the fans. It is a electrical sound. -
The reason I bring this up is I have the compact razer supply in my case to only use when away from home. At home I use some old larger supplies so I don't have to pack and unpack mine all the time. I wouldn't know about any sounds from the compact supply since I haven't used it yet but I would have thought I would have noticed a sound coming from the notebook itself. -
Thanks guys. I just dropped my computer to Fedex and it will be shipped back to Razer. Let's see if the problem can be solved

Ticking sound is most likely fluid in the heat pipes vaporizing. I had a warranty repair on my 2013 for this. They will probably just replace the heatpipes. Support advised that ticking is expected if you start the computer on a level surface but then in use tilt the laptop. Even after warranty repair I can replicate the sound by tilting the laptop however it does not do this when used on a level surface.

Also, I've now had this randomly happen to my 2014 RBP, just knocking on the top of the chassis stopped it. I just don't understand what causes the vaporizing liquid to cause the ticking, but I can see how, if that information is correct, the notebook hitting excessive temps could start it going. -
To make notebooks thinner, smaller, but higher power at the same time, heat pipes are getting thinner, flatter, and have tighter bends. During fabrication, the wick on the inner surface gets damaged, and there may be a "bare" spot defect that does not get adequate fluid flow. During heat-up, like after booting or when starting a game, fluid at the bare spot will boil rapidly causing a popping sound. Tilting the notebook can also cause more fluid to flow to the defect accentuating the popping sound. Once the notebook is at temperature, the defect is probably bone dry so there won't be as much noise. Without the defect, the wick replenishes the fluid to the hot end of the heat pipe efficiently enough that there is no rapid boiling, just vaporization, so no popping noise.
Incidentally, the noise in the video above is certainly electronics noise, I think from the capacitors, but the inductors may also make some noise. It could be the manufacturer is using cheaper components, and since there is a limit to footprint and height in such a thin high powered design, they are probably pushing the components pretty hard. -
if it is a capacitor or anything the like, can it get worse in time? -

Now I just have to monitor the notebook under stress and see what falls out -
I don't believe the sound will get worse with time, since it depends on the frequency the cap is being driven at which should not change. I don't know if there is any connection between capacitor noise and reliability. The noise is actually caused by the interplay of the capacitor with the PCB it is mounted on. Here is a good description on the cause of capacitor noise:

That is most certainly coil whine as noted by other members. You might have more or less with another unit but the increased perception of this by some users probably has more to do with the test material than the unit itself.
