Franzi Posted May 4, 2013 Share Posted May 4, 2013 Hi Corsair & Community I'm running my i5-3570k at 4400Mhz with 1.2v (Offset, 1.184-1.208v during full load). My new H80i unit came with the 4 pin fans, I assume they are the new PWM version. I didn't install the Link software yet so the fans are running in the balanced/default profile. Its installed in a Silverstone FT-02, exhaust direction due to the positive pressure of the Case. After 20 minutes Prime95 the max core temperature was 65°C on the 2 inner and 61°C on the 2 outer cores. My room temperature is about 24°C. Are these temperatures good or a bit too hot for 4.4Ghz/1.2v ? I'm just curious because Corsair claims on the H80i product page an i7-3770k at 4.6 Ghz would be running with a temperature of 47.94°C. Not sure which temperature they're using. Kind regards Link to comment Share on other sites More sharing options...
peanutz94 Posted May 4, 2013 Share Posted May 4, 2013 First, you have a differnt CPU and they all will act differently even across same part numbers. The graph on the product page is not a "claim" just a comparison between the Hseries coolers and the stock. cooler. They also don't list what they used to determine those temps.What system it was tested in and how many CPU's they used before they got one to run that cool. With the CL software the temps of the coolant in the CPU can be read and are always quite a bit lower than actual CPU temps. They don't say if that is coolant temp or actual CPU temps. Which will also be different from actual core temps as well. You are also running 32gigs of 2133mhz memory and that will also add to your CPU temps because of the load placed on the internal memory controller. At any rate your temps are not that bad. But again a lot will determine your actual results. Case fans, case used, air flow, and so on. Their test system was most likely a bread board rig for testing purposes and will always be cooler than what is actually installed in a case. You could try re-seating the pump head with fresh thermal paste and see if that doesn't make any difference in your temps. Also be sure your pump is running where it should be .

Franzi Posted May 4, 2013 Author Share Posted May 4, 2013 Thanks for the reply. First, you have a differnt CPU and they all will act differently even across same part numbers. Not by over 20°C... Would be interesting to know if they mean core temperature or another sensor. You are also running 32gigs of 2133mhz memory and that will also add to your CPU temps because of the load placed on the internal memory controller. I'm not running that memory. I asked something about it once on the corsair forums but returned said memory kit a day later. Right now its 16GB 1866/C9 at 1.5v (Dominator Platinum as well). I looked up a few more reviews of the H80/100i units with Ivy Bridge CPU's and their temperatures were even higher at similar voltages so I guess i'm alright with 65°C max, 50-55°C normal load like video encoding. The pump/heatsink can be installed in any position? Since my case has vertical mounting the pump is also in a different angle, with the 2 tubes to the bottom.

Franzi Posted May 5, 2013 Author Share Posted May 5, 2013 Thanks again, thats good to know :) Im still running the fans at the default profile without link software, at higher speeds the temperature will probably go down another 4-5°C but 65°C during stress tests is alright for me.
