You would likely get a more accurate response from Mayhems, as the question is far more fluid specific than hardware specific. They monitor here - https://www.overclock.net/forum/61-w...sers-club.html
There is also a a Swiftech club here - https://www.overclock.net/forum/61-w...ners-club.html
Swiftech claims three years when it is left stock, a fluid change obviously changes that. Even with the stock fluid, I always changed out at one year.
