hi,
im thinking about overclocking my GPU (gigabyte GTX 1080 windforce)
My plan is to cool it with the NZXT Kraken X62 with the NZXT Kraken G12 bracket

https://www.newegg.com/global/be/Product/Product.aspx?Item=9SIA0ZX6BK0043&cm_re=NZXT_-_Kraken_X62-_-35-146-059-_-Product

https://azerty.nl/product/nzxt/2665179/kraken-g12-waterkoeling-92mm

BUT
is it really worth it?
I heard that while the chip in the GPU is cool the rest isnt getting cooled that well. is this a big problem?
the stock cooler on the 1080 ist that bad ether (trippel fan)

I want at least a 15% boost in performance

Yeah....VRMs get warm, as does any active component.....but first of all....there is no direct way to cool them as far as I know....like....you aren't going to slap a cooler on a VRM. ...and secondly....it's not like VRMs are failing all over the place because they get too warm.

...and as far as I know....VRMs don't generally even have a temperature sensor to monitor....so how are you going to know if it's even "too hot"?

I've never focused on cooling VRMs....on a motherboard.....or a GPU.....and so far I haven't lost a VRM due to heat from the indications I've seen.

Well...you could start overclocking it and monitor the temps and see what happens.

If you start getting above 75-80.....you need a different cooler.

"I heard that while the chip in the GPU is cool the rest isnt getting cooled that well. is this a big problem?"

The rest generally doesn't get that hot.

The GPU chip is the most importand part to be cooled, the PCB and the rest aren't that "importand" but cooling the whole GPU doesn't hurt it and some people claim it can extend the card's lifespan when it's exposed to less heat, I do always recommend to people to keep VRM's cool aswell, they can get very hot espically when you're overclocking but if you have very good airflow in your case then then there's no problem.

u sure? if seen several people say that the VRM's get pretty hot to.

VRM's do have a tempture sensor and I believe they can be checked with GPU-Z, I know MSI Afterburner and SpeedFan don't support it, I'm not sure but other monitoring softwares and VRM's can fail very easily on older cards that are less power efficient as far as I know, this is not a common problem with 10xx and 9xx series cards but for example 6xx series, has a seperate heatsink for VRM's and MOSFET because they do get hot, both in refrence coolers and even EKWB full lenght waterblock (I know this because I have watercooled SLI GTX 670's) I also believe 7xx series cards have a seperate heatsink for VRM's and I am pretty sure on 7xx series cards, the VRM's were moved from front of the card to back so they are near the blower fan on refrence cards to keep them more cool. Long story short, VRM's can fail due to heat but it's not common and it's more common on older cards, and if they don't fail, you can notice un-stable voltages. If you wan to read more, EKWB has a really good article on GPU and motherboard VRM and why they should be cooled, you can find it here
