Hi all, new here so please excuse my lack of knowledge. Just completed a new build, have built a few over the years, but my years are also getting on. Since I built my last machine in 2011, things have changed quite a bit and I see new things I didnt before, therefore am having difficulty. Please also accept apologies for rambling long 1st post !

New Spec:
ASUS A170-Deluxe
Intel i7 6700K CPU
HyperX Predator DDR4 x 16Gb (3000Mhz)
Kraken x61 Cooler
NZXT Noctis 450 Case - Matt Black
EVGA 850W P2 Platinum PSU
Samsung 850 EVO - 250Gb Boot Drive
Samsung 850 EVO - 500Gb Steam/Origin Drive
Cronos SSD x 2 - 250Gb (Just because come out old build and have space)
WD Black 3TB - Work files (Press Photographer)
AMD R9 290 Graphics Card (out old machine - will replace after xmas)

Now when I was building I spotted a video on YouTube regarding the build I was doing and the same mobo, case and cooler there, and the video was on the ASUS Site.

While watching the engineer placed the Kraken on the top with the fans blowing down INTO the case ... which I duplicated.

My first issue was then the wiring up of the fan controller thing on the back of the case ... which was conflicting with the information supplied rather poorly on the Kraken x61 cooler.

Currently Cooler is connected to the mobo CPU_FAN header and not directly through to the fan controller on back. The SATA lead from pump is connected and the USB is connected also. The fans on the cooler are then plugged into the fan ports on the same cable as the SATA power cable, not directly into the fan controller thing itself.

I keep seeing a term called PWM which I dont understand either.

So, once built, powered up, installed Windows 10 x64 as I purchased a copy of it ... yeah I know !!! it turned on fine and all was well ... or so I thought !

Into the BIOS to check everything was as it should be .... and only one fan was registered as spinning, and it was the CPU fan and hasnt moved from around 750-790 rpm, none of the other fans are showing any data :confused:

I look in the fan stuff and the curve and seems ok, but what do I know? The BIOS is completedly different to anything Ive seen before and the fan section has a choice of PWM or DC ... its selected as DC at present.

The RAM was listed as DDR4 and 2133Mhz also, so I changed that to 3000Mhz and that was all I done, rebooted, and nothing worked again. Failure to boot due to OC failures, CPU LED on motherboard, and also saying RAM no itinitalised. After 2 days ... I decided just to switch off and start again, but after I flashed the BIOS to make sure sitting on latest version which it is now on 1302

Whole reinstall later and back up and running.

Now ... keeping up :(

Everything on and working, sides still off case basically just the chassis.

Idle temp sitting 19 - 21 degrees, and I was happy with that .... playing Black Ops 3 ... it was around 58 degrees after half hour.

Put everything on, the covers etc ....

Idle temperature 22-23 degrees but the playing BLOPS for half hour has the top core sitting at 68 degrees !!!

I thought that was ok ... but remember old system temps were sitting at 59 under big load (i7 3770K) and Corsair cooler

So i decided to follow instructions and reverse the fans on the cooler so that it was pushing air up from inside case to outside case basically across the radiator.

Put all back together, sides and lids on ... and proceeded to test again.

24 degrees idle and tonight a 78 degree temp across a core (see pic if attached correctly)

It just doesnt seem right, so I am guessing I have done something wrong.

I havent attempted to change anything in the BIOS as I need a working machine for my accounts, and work, and 2 days downtime previously was a nightmare.

So ... any pointers to this 41 year old noob thats lost touch with what terminology is and new tech ...lol

Questions I will answer as best I can if I have missed something above as I don't want to melt the machine especially with Battlefront already pre-loaded and waiting lol
 
68 seems normal to me

I would point the fan to blow down on the heatsink

The radiator is in the top of the case with fans on underside of it. I can't see how they could fit in top of the case to blow down onto the radiator??
 
I take it when you reversed the fans on the radiator you just turned then around and didn't change turn the radiator and fans around together?

With a radiator I would always have the fans blowing through it. So if it's in the top of your case it's should be - fans, radiator, case.

I have a fan hub in my case and the fans don't register any speed on any software I have used. If I change the speed you can hear and feel the difference so they are working.

Maybe the gpu is kicking out a lot of heat. The first pictures you posted don't seem to have any problems in them from what I can tell.
 
Hi, thanks for that.

When I first bought case I mounted the radiator on outside of case with the the two fans drawing off it but didn't think to try the case lid to see if it all closed up. So then moved it to inside of case.

It was build as per the ASUS YouTube build video


Using your method of fans / rad/ case is that on inside of Case chassis or on outside of chassis?

The CPU does seems to chuck out a fair bit of heat and the plastic on the cover window does become warm/hot to the touch during a session.

I still have my Phantom 410 case but that was ridiculously loud and one reason I decided on a new more silent one which this new build is.

I'm just concerned about the 70 degree temps of CPU as I can't find any info of load temps online or I'm not looking in correct place.
 
OK thanks, I will see if there is a way to move the fans from inside the case to the outside of the chassis blowing onto the radiator inwards towards inside of case instead of blowing what could be warm air across a radiator from inside the case to the outside through rad.

with the fans/rad/case i would always do this inside the case. where did you mount the rad and fans outside of that case?

where are you going to mount it now? you should be able to top mount it inside the case.
 
Hey thanks for reply.

I basically originally placed it ontop of the chassis between the top and the outside cover .... before realising the error. Here is what I have ...

1st Time Installed - at top of chassis on inside of case with fans pulling air off rad INTO case.

2nd Time Installed ... Same location, but fans reversed to push air up through rad to exhaust out top of case.

Now I also grabbed the CAM software after reading another thread here, and had a 40 minute session on Battlefront with CAM running in background, and the CPU top temp reached 86 !!! ... I am thinking that is very high, although I noticed that the fans were on SILENT Mode ... cannot see if there is an option to place on auto so that as things get hotter, the fans spin up faster???

Thanks for all your patience with me.
 
CAM software? what is that?

my motherboard is Asus so it uses software called ai suite and it has some extra software inside called fan expert. that allows me to change the settings for my fans.

86 is definitely high. and possibly too high, if that was my cpu i hope it would have shut itself off before then.

EDIT - fans look nicer aswell when you put the to push through the radiator.

i cant find anywhere the max safe tmep for that CPU. i seen a mention of the i5 from same generation having a limit of 73 though. but nothing on the i7.

Only problem i can see with that setup is that although the fans are doing the right thing, pushing air through the rad, the problem is, is that they are pushing the warm air from inside the case through the rad!!

CAM Software is from NZXT ..... the Noctis case manufacturer

My board did come with AI Software too, but havent used that as the only fan that was controllable was the CPU one, and the other 3 on front and one at rear was not showing anything on, although they are turning.

I may re-install as I had forgotten about that after the re-install.

On the cam software I also made a custom profile so it works the rad fans now at 100% once CPU temp hits 60 degrees, although the game of Battlefront there seen a 71 degree temp.

I am also like you I cannot find a temp scale for the i7 !

Yup, I agree .... and when I watched the build video on youtube from ASUS it was showing the rad fitted on the inside, top of case with the fans pulling air from the rad but venting INTO the case itself ....

I just dont know what to do to make this cooler on the CPU side of things?

I dont know what I am not doing thats causing the higher temps :(

Airflow! You need better airflow. That case looks too enclosed

Its the Noctis 450 Case, have I wrongly assumed that the three fans on the front would have created a good throughput?

Can I improve on the airflow on this case?
