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.
Im thinking of geting water cooling for my pc and ive been looking around for a pump for the system but they are quite expensvie like £45 would an aquarium pump work as they are much cheaper
In general yes, the Eheim pumps are still widely used and considered the "best" of that class. Be careful you don't want a submersible that must be underwater. A good high quality aquarium pump will certainly do the job (and have done so for years before the specialty pumps came about).
