Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
What I have read from users its not worth it do to the unbalancement of performance: price....and a few other bad things
Consider the MCT-40 from DangerDen if you can get it in stock! So far based on user reviews its the best of the non conductive products without the cons produced when using fluidxp
As long as you are careful when building your loop and leak test everything for at least 24 hours, there isn't a reason to get something like FluidXP. Distilled water will work just fine, and cost 80 cents as opposed to 40 bucks.
