I understand, but what is your point and why are you scratching your head? The 620 is a decent cooler but stellar temps are not to be expected from a low end cooler designed for average users with average CPU clocks. Better temps can be found from an H80 or a Kuhler 920... Stellar temps under a heavy OC usually only happen with a well designed custom loop. A Hyper 212+ and a Kuhler 620 are just not all that different in terms of the heat they are able to dissipate, and results vary from user to user based on installation method and ambient temps, to some degree. headscratch.gif

Yeah I didn't see his overclock. My bad. I was just saying I saw a pretty good drop at my overclock.

But it's not doing its job when I approached 4 ghz and so now I'm in the market for an actual water loop.

The H70,620, and 920 are Very much a Performance Cooler with the added benefit of Silence. The 620 Keeps my friends 930 OC to 4.2Ghz at 45C Idle and 68C load while playing games. In Prime it went as far as 78C - 82C tho. With Push Pull setup I would pick these things over any 1 ton air cooler that hogs a large amount of space. Unfortunately thats not the case since I have had consequently 4 back to back Kuhlers with Bad Pumps. frown.gif Other then that they are pretty sweet smile.gif

The 620 and H70 are not "performance" when it comes to water loops. They are small, self contained, maintenance free, closed water loops that are meant for silent computing and cooler temps at stock speeds or lower overclocks. The H80, the 920, and H100 are performance water loops which are capable of keeping even the hottest, highest clocked chips cool under heavy load - within the limits of normal 24/7 overclocks and even slightly beyond. Granted I suppose "performance" is more personal opinion than anything, seeing as though none of these coolers are really labeled "performance CPU coolers" in the grand scheme of things. I suppose you can call it what you like, but the point I was trying to make stands - And this point is, if the Kuhler 620 is disappointing, then buy a better performing loop and that will change. Please don't try to educate me on the capabilities of either the 620, the 920, or the H80 which are only coolers I've mentioned because I own and have experience with all three units.

I did some good old testing today and i do a stable 73c on ibt with a custom load of almost 15gb of ram... No program out there can top that load or the heat... With no intake fans either... Only with a push configuration on the cooler out of the case...

Here is my research so far...

CPU is running 1.35v too pretty good cooler if you ask me...

Hey Birdman,

I've been reading about your issue, specifically, a rattle that appears to be located in the vicinity of the pump unit/CPU. You have changed out the Khuler four times, and yet the rattle still exists!

A few questions...

Q1: Have you had this rattle happen on different systems that use the Khuler, or have all four Khulers been installed only in one (the same) system?

Q2: Have you gone around inside the case while the pump is mounted and running, and tried pressing down on various components and areas around the pump to see if they have any affect on the rattling noise?

Q3: Have you tried re-mounting the (rattling) Khuler in a different case on a different mobo, to see if it rattles in that install?

I will assume for a minute that the answers to 1 and 3 above is No; that all have been installed in the same case and mobo, and not re-tried in a different host PC before returning the units.

While I have little doubt that you have been both diligent and thorough in your efforts to diagnose your 'rattle', I must say that your receiving a fourth bad unit in a row, is extremely unlikely and so far off the charts statistically-speaking that it really points to some other problem in your system.

I suggest the problem is not defective units(!) from Antec, but rather is a problem with your CPU, motherboard, or case.

Certainly, these pumps produce at least a little vibration. But the majority of Khuler owners - by far, (and myself included) - have complained little or none about the chronic rattle you have. What I hypothesize is that the pump vibration is rattling the CPU itself, or the CPU chip ZIF socket on the motherboard, or components adjacent to the CPU, such as the VRM modules, the chokes, or the caps. Or, it is vibrating the whole motherboard and perhaps the khuler back-plate is touching the motherboard tray and rattling there, OR one or more mobo standoffs are loose on the motherboard tray (check for these!). It's even possible that your mobo has some sort of internal de-lamination between board layers and that is amplifying the vibration from the pump.

Take a few steps back and re-assess the situation. Assume the Khuler isn't bad; rather that, there is something about how the Khuler, the CPU, the mobo, or a component on the mobo is mounted such that they are vibrating and/or rattling against something. While you may have been pressing on components and areas around the pump to try to isolate the noise, I'm convinced something is not right in that area and more pressure may be needed or something has been overlooked.

Four bad units in a row just does not happen, unless the units are being drop-kicked (every time!) by UPS, or by your landlord/wife/roommate, or you are somehow (inadvertently) mishandling the unit each time you install it.

But I think it is not you or UPS at fault, I think it is a defective mobo or physical mounting issue (a badly mounted or defective CPU ZIF socket, or a bad choke, or a bad NB/SB heatpipe-heatsink-mounting-cooling fan-whatever). I urge you to look for something like that, extremely closely, before suspecting the (fourth!) cooler of being defective...meanwhile, you have my sympathy. mellowsmiley.gif

Regards,
-Krunchy

NB: One last idea - did you use the foam tape to mount the backplate? If not, that's another suspect - the backplate might be vibrating against the mobo).

Hi Antec Kuhler 620/920 members

 

I was wondering is it easy/possible to change the tubing on a 920? Also, if the tubing can be changed, can the wiring for the fan controllers be extended to allow me to put my 920 into different parts of my case?

 

Thanks in advance

anything is possible, however anything you do to it will void warrantee. Run it how it is for now.thumb.gif
