Or, get a better case with tons of cool air coming in (Antec 300 is a cheap, effective example) and then run the rear and top fans as exhaust with the front two fans and the side fan as an intake. The cooler the air going through the radiator, the cooler the CPU will run. Also make sure your fans are running at a high enough speed to keep the liquid cool enough so that that CPU is within the range you would like it to be in. It's easy with the 920 software, but not hard with the 620.. just control the fans in the BIOS if you have to and set them to run faster if necessary.
My girlfriend has the same motherboard as you, and you can control the fans in the BIOS. Let me know if you can't figure it out.
I actually have Three intake fans on the front and the side fan is exhaust.


Hhhm, come to think of it i did reset my bios the other day and smart fan might still be on on the CPU_FAN header rolleyes.gif

Three fans sounds great to me.. a top fan running slowly for exhaust wouldn't hurt keep the heat out of the case when the CPU fans are running slowly - worked well for me anway..

But yeah, smart fan is likely to make the liquid hover warmer than you might want, resulting in high idle temps. I'll bet load temps will remain just fine - but turning of Q-fan will lower temps all of the time I'm sure thumb.gif

Just info, FYI type of thing. smile.gif

Thanks for this.

"Why should I use "Core Temp" and when?

AMD designed this equation to accurately read peak (45C+) and load temps. It has an equational offset to determine said temps which equalizes at 45C. Since it's designed for peak temps and is a non-physical temperature it cannot read idle temps or account for ambient temps correctly.

So what is "CPU Temp" good for then?

At peak temps this value is typically 7-10C higher (depending on motherboard) than the actual temp due to it being a physical sensor. At idle it's a little more accurate, but still not dead on, and besides idle temps do not matter near as much as load temps do."

So in your case, your idle temps may be 38C or so, mine are too.. granted I'm OC'd quite a bit but you also have two extra cores. Your idle temps and mine seem about normal - and it's normal for water cooling to idle a bit higher than air cooling - max temps are what matters and we both have improved max temps.

What AMD is saying about the 45C / accuracy thing is that the further below 45C - the less accurate the reading. They go on to say, however, that the core temps typically read 7-10C lower than the MOBO-CPU temp reading (in my case it's 8-15C difference) and so under load we can look to core temps and just worry about those keeping below the 60C limit on these chips.

So yes, you were right and thanks for the link / explanation. But no, your temps were not abnormally high while idling or anything to worry about - as I stated originally, right?

Again thanks for the link thumb.gif

At my current OC I can't get the cores over 37C, at that temp, the MOBO CPU reads 60C so in my case I'm not even heating up to the point where the cores can accurately display their true temps.

They weren't overly high but in my opinion they were abnormally high in comparing the install versus my HDT cooler (Xiggy). After subsequent re-seat and adjustment it seems it's working exactly right now, perfectly too.

I am clock limited by my motherboard. I'm fairly certain it's a power issue and chipset limitation too. That's fine though, I'm good where I'm at. smile.gif

I don't see the same kind of extreme difference in readings as you do but still far greater. Because of this I tend to gauge temps more closely with the CPU versus the core reading, as it's roughly 10-13 in difference for me. In that respect, I'm all good.

Yeah, AMD guy says once you're under load and over 45C on the cores, just watch core temps and keep them under 62C, or 60C for extended periods. I wouldn't say 10-15C is extreme as it's actually quite common, but yes it's a big temp difference - it makes sense if you understand where the diode is placed on the CPU socket and that it has no way of being directly cooled.

Yep that was it...
was running at 9xxRPM now it's back up to 13xxRPM thumb.gif

Yeah, I'd like to get atleast like a 140mm for the top (if it has the holes for a 140)
since I'm sure I cant run x2 120 of a 200 with the Kuhler rolleyes.gif

And what was that about a Antec 300?
does the HAF912 not have very good air flow?

Your case has excellent air flow - I actually didn't look at the case in your sig rig, my bad. But yeah, a 140mm fits fine there I think, run it on a low to medium speed, as not to suck too much air from the intake on the radiator.

Glad the issue was just the Q-Fan setting smile.gif

Hi everyone, brand new member to this forum.

So about a month ago, I built my computer and put in a Kuhler H20 920 with Green Coolermaster Silent fans, and about a week or two ago I got the dreaded clicking/gargling noise (I've made a video about it- http://www.youtube.com/watch?v=jf5otnEgXbU). This morning, I was reading this thread about some people having the clicking noise, and don't quote me on this, but I inadvertently did something and all of a sudden the noise has stopped.

I read someone's post where they suggested that you plug the Kuhler fans into the motherboard and not the Kuhler. So I opened the case, unplugged the fans and plugged them into the mobo, but I also unknowingly unplugged the fan header which I think runs the pump. I fired her up and left her for some 10-15 mins.

I come back to the clicking noise, and I check the temps... Antec ChillControl was reporting some 55-60 degrees celcius (when it's normally 30 or under), and HWMonitor reported 70 degrees celcius on my 2500k (normally 30-35 degrees). Something's obviously wrong, so I turned it off, undid the changes and turned it back on, everything was fine... About an hour later, I realized there was no noise (the noise would always come on not even 10 mins after turning the computer on). Right now, I've had the computer on for about an hour and so far, so good.

I think what may have happened was by unplugging the pump, the coolant wouldn't have been able to be pushed to the radiator, so it couldn't be cooled, and because hot air rises, the air pockets may have risen and been bled out. Although I'm not sure if hot air rises in water. It's far too early to say whether this may be a definite fix, but we'll see. If anyone has exhausted every other option, can't or don't want to RMA, and want to risk giving this a go, please please please keep an eye on your temps and make sure your CPU is not overclocked. My 2500k is at stock speeds and was pushing 70-75 degrees celcius. Do this at your own risk, I won't be held responsible for any damaged hardware.

PLEASE, NEED HELP WITH THIS!

Okay you Khuler owners, I need some serious advice regarding these coolers. I plan to install one of these coolers on the outside rear of my Fractal Design Core 1000 case. I'm only interested in maintaining a max 4.5GHz OC with my 2500K. Which Khuler would be best for my desire. If the 620 is efficient, would a pair of GT-AP15 or Swiftech Helix be perfect (even on the 920)?
