Vengeance616 Posted August 7, 2014 Share Posted August 7, 2014 Hi all, a couple days ago I moved the majority of the components from a gaming rig built in May to the NZXT H440 case with the new i5 4690k, MSI z97 Gaming 5 Mobo and two noctua nf-f12's in pull config. Primary reasoning behind this was because the i7 4770k in the old build was a horrible chip that drew 1.272v for a 4.2 oc. At the time I thought that temps in the mid/high 80's during prime95 testing was due to the power draw. However with the transition to this new build, I am seeing very similar temps and even higher idle temps than with the i7 cpu. Specifically, before I was getting mid 30's idle and mid/high 80's under full load. Now with the i5 4690k drawing 1.12v for a 4.2 oc, it idles at 40 and reaches 80 under full load. Should I RMA this as a faulty h100i? I have reseated it 2 times now using Artic silver 5. Both times on initial boot after reseating, I noticed that the idle temps were in the low 30's. Upon stress testing, the temps started in high 60's, but eventually climbed to high 70's. After a reboot, the idle temps would stay in the 40's and load would remain mid 70's till reaching 80. So the initial boot temps seemed promising, but would never reach the same low temps after a reboot. I have made sure that the backplate is installed correctly and I have ensured good contact between cpu and heat sink. Looking at Corsair Link, the pump RPM is normal but during prime95, I noticed that the CPU liquid temp rose from mid 30's to low 40's which caused the slow increase in CPU temps from mid 70's to 80 under load. I'm not sure if thats a sign of a bad pump, or if thats just normal. Therefore, I can only come up with 3 possible solutions based on searching the web: 1) Reseat with different TIM like IC Diamond 7 2) Try the rubber washer fix (But I see no reason to since the backplate is firmly secured after installing the heat sink) 3) RMA Here's a link to my build with some pics. https://pcpartpicker.com/b/sDxYcf I have some pics I can upload of my most recent reseat but I doubt they'll be very helpful. Really hoping someone has a solution for me here that doesn't involve RMA. Thanks for reading! Link to comment Share on other sites More sharing options...
Dave65 Posted August 13, 2014 Share Posted August 13, 2014 Them fans you are using are they static pressure fans? Link to comment Share on other sites More sharing options...
snapper69 Posted August 13, 2014 Share Posted August 13, 2014 They're 2,61 mm H2O and VERY quiet. Although they don't look too good in baby poo brown. I've got 2 mounted on top of my rad, pulling air up and out of my case and they work well. Link to comment Share on other sites More sharing options...
Dave65 Posted August 13, 2014 Share Posted August 13, 2014 I don't know if those are static pressure fans but that is what you need with a closed loop cooler. Link to comment Share on other sites More sharing options...
hurricane28 Posted August 13, 2014 Share Posted August 13, 2014 Yes they are static pressure fans... they are not that great on radiators because they only have 55cfm and the static pressure is not optimal for this kind of radiator. The standard fans of this cooler have 4.0mm-H20 and the Noctua has 2.61 so thats an huge difference. So use the standard fans that comes included with the cooler or get some higher static pressure fans. Link to comment Share on other sites More sharing options...
snapper69 Posted August 14, 2014 Share Posted August 14, 2014 Maybe so, but that 2.61 is produced at only 22.4 dBA rather than the 37.68 dBA that the standard fans produce. Link to comment Share on other sites More sharing options...
Vengeance616 Posted August 14, 2014 Author Share Posted August 14, 2014 I tried reseating with nt-h1 and got mid 70's temps so I might have gotten a bad batch of AS5. I just switched to 3 noctua intakes and a Cryorig R1 Ultimate and I idle at 33 and max at 70 on prime95. I think it was bad airflow in the case, bad tim, and a bad pump. Anyways, I'm probably going to RMA this after all :/ Link to comment Share on other sites More sharing options...

Were not talking about noise but performance.. Its very simple, if you want the best out of these high density radiators you need to go push/pull with high static pressure fans OR with a set of 2 very high static pressure fans. Under 4.0mm-H20 it simply will not perform well... Link to comment Share on other sites More sharing options...
snapper69 Posted August 15, 2014 Share Posted August 15, 2014 I have a pair of NH-F12 fans mounted on top of the rad sucking air out through the rad and out of the top of a 750D and the temps are mid to high 20's on idle and a max of 60 when testing with Prime 95 This is with a 3570K @ 4.3. Seems OK to me. Link to comment Share on other sites More sharing options...
