Howdy great peeps,

Installed my H100i today on the I7 4790K (I think, however, I didn't seat it properly, since the screws are a bit off & when I installed it I noticed I touched the thermal paste, since it was on my hands - the protection package came off apparently somewhere along the line),

Anyways,
did a Prime95 short test, my question is:
Are these temperatures allowed? (It is about 25c-30c in my room & mild 0.4Ghz OC)

Looking forward to a reply & thanks,

Corsair H100i Cooler & 2x Noctua NF-F12 fans
I7 4790K CPU

good catch~ i didn't look up your fans and you're right... good rad fans there. So then if redoing the thermal paste doesn't work your next check is to make sure the pump is running at 2100~ish rpm. that's the speed a the pump on a h100i is supposed to run at.

your fans are "pushing" air right?

how hot is it inside your case?

i'd redo the thermal paste. that is quiet high... granted this is prime95 and you're using a hot little haswell... but it's better safe then sorry.

your next test would be to see if the h100i is hot. if it's hot then those noctuas are the wrong fans to put on a water rad. typically noctuas make good heatsink rads and case fans... mediocre water rad fans. static pressure is what you need from a fan for a water rad... and noctua fans are average at best. you can test if it's the fans by trying the stock corsair fans and see what happens.

better get yourself a new temp monitor as these arent real temps.you are not going to get the temps below the ambient room temp,so unless your room is pretty cool i question these temps.to the original poster,as far as ive been able to gather these temps are not out of line.you will probably not reach them when gaming as prime 95 pushes your cpu pretty hard.that having been said,did you fix your original install problem ie reapply paste and make sure the heatsink was seated properly?

Are you playing in a freezer? I'm thinking your sensors are broken.

To OP, I get about the same temps as you but i have the i7 4770k and a NH-D14 cooler (pretty comparable in performance)... I get slightly lower temps than that on prime95 at the same Clock rates.. I would expect the i7 4790k to run cooler than the 4770k - you might want to redo your thermal paste your temps seem to be about 5-8c higher than i'd expect to see but not a big deal those temps are perfectly fine.

Well the Noctuas I use have a HIGH Static Pressure (designed for Radiators - NF-F12s).
They are the best after market fans for the H100i.
Did extensive research about this before buying.

But still these temperatures are quite strange.. :(

Howdy again,

Well the fans are pushing air running at 1300RPM constantly.
Inside the case it is about 30c-25c

How do I check the pump ?

well, the h100i has that corsair link software. you should be able to open it and see what speed the pump is running at. If it works anything like the h100 works, you can also simply hop into your motherboard's bios or use HWmonitor and check out the reported "rpm" coming off the cpu fan. that apparently is the "rpm" of the waterpump.
