GPUs on Water, how long will they last? (potential OC)

[priviet]

Hi,

I read the other "how long will they last" thread and I've a similar but different question:

My noisy GPUs are all on water with a monster radiator (Phobya Supernova 1260 / 4x 200mm Fans) so they chill around 45° C all the time with max OC. The question: is it safe to OC / Max out the Powertarget 24/7 without increasing the voltage?

Sapphire RX480 Nitro+ OC 8 GB (ETH)
Zotac 1080ti (ZEC)
Gigabyte 1070 itx (ZEC)
VTX R9 290 (ETH)

and a XEON 1660 (Hexacore) for XMR

Efficiency is not a question for me!

PSU are Tier 1 ones with lot of headroom!

Looking for interesting answers / discussion

Usually miners never overvolt their GPUs. When overvolting it uses huge amounts of more watts and the difference isn't worth it in hashing speed.

Not planning to overvolt but especially the Nvidias can go 120% PT and e.g. the 1080ti can do 2050 Mhz+

Overclocking without increasing the voltage is totally safe.
Just keep increasing the overclocking in small amount to know the limit of you GPU, over the limit GPU won't work (until reset).
