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.
i've looked into the swissflow one and apparently it causes a substantial pressure drop. From the research i've done all flow meters have relatively high impedance so i'd only do one for vanity. if you're trying to push your system as hard as you can it wouldnt help you.
back on subject....
it was my understanding that the G7 was actually designed to work very well in low flow situations. I recall it being one of cathar's goals in the design?
tests done by cathar. and while it may not make that huge a deal dumping heat into the system DOES affect how effectively the CPU is cooled, in a system where everthing you do tries to remove heat added heat does not help.
nice pump, only problem is that it dumps more heat into the system then the D4. but it is a killer pump.
EDIT: also techincally i dont belive this is a D5, i'm pretty sure its just a new model of the D4. i'm not 100% though
ya, mirror finish doesnt matter, its flattness that counts, i have seen mirror lapped blocks that are warped like a mother. plus there is such a thing as too flat. if it is too flat the thermal paste has no where to go and you get worse cooling. i'd hold it up to something straigt and look at...
first of all, that looks a hell of a lot like green, which is one of the two colors that copper corrodes to (green and black) it also looks like corrotion. even if that block is all copper/nickel/brass if you are using a AC rez that ic Al and will cause it as well.
might i add taht that block...
i was saying i didnt like AC because they used Al and Cu. Personally i'd go for no Al in the system as Cu is much better as you prolly already know. Putting Al and Cu in the same system is deadly and will cause corrotion a lot faster then an all Cu or all Al loop. Brass is ok, it doesnt react...
if i were here to tell you i would have said i told you so. copper+alluminum in the same system makes the likelyhood of corrotion is increased greatly.
