Mugen 1000 vibrates
Hi, I have installed the Mugen with the retention kit on a 775 board.
Got the cae on the desk and can feel the whole desk vibrates, so checked were it came from and when I lay my hand on the Mugen's metal plate I feel it vibrates. Is this normal? Guess not, but why does it do that?

Regards, relikwie.

Hi relikwie,

do you use the original fan? If yes, is the fan okay?

Hi Stefan, everything is original as far as know. The fan seems OK, doesn't produce much sound and rotates ok.

There is something else I just saw. The mugen does not seem to be aligned relative to the case and board. See following images.
It is firmly mounted using the retention kit, just wondering if I maybe did something wrong. I used both the plastic spacers and the copper plate.

Anyone an idea?

Have put the fan at 800RPM now since 2000RPM vibrates the CPU Cooler.

Which fan do you use? The Mugen is delivered with a 1200 rpm fan (max). If you have a fan that's capable of 2000 rpm this is definitely not the stock fan of Mugen.

I wouldn't wonder that 2000 rpm causes vibrations. That is more speed than Mugen will need anyway.

Perhaps you should exchange the fan for the stock Slip Stream 1200 or a Scythe S-Flex with the rpm you need (depending on your CPU 500 or 800 rpm will be enough).

If you mounted Mugen with the Ret Kit it is absolutely stabil. But depending on your case probably part of the covers could be vibrating especially if made out of aluminium. The Mugen is tightly connected to the board via Ret Kit and the board is connected to the case with screws. And the fan itself is also fitted tightly to the Mugen with its fan clips. So this is a complex unit and vibrations can easily find their way from one component to the other. But normally no fan running at 1000 rpm should do so much vibration so you should check if the fan is really ok.

If you say 2000rpm, you surely can't have the original fan. Please note, that it is quite normal, that a fan with 2000rpm starts to vibrate.

Hello, first I have to say that I am not completely sure is was 2000 RPM.
It could have been less, but I'am sure of that I have set a setting in the BIOS that controls the CPU fan (from auto to voltage). And since the RPM is around 800 and vibrations are gone. I'am using the fan which came in the Mugen 1000 box, as you can see in the picture in my second post.

I also took more pictures to show that the cooler is not outlined correctly in relation to the mainboard (it doesn't seem to be aligned with the edge of the board). Thinking maybe I mounted the retention kit wrongly or whatever I have could have done wrong.

Also I didn't dare to tighten the screws on the backplate that much, afraid of braking somthing.

My CPU is a E8500 @ 3.16GHz currently. But was planning tio slightly overclock this to a 3.4 ~ 3.6GHz. Would 800RPM be enough for this?

Your temps will decide that - these are the only relevant values. So overclock and check your temps when using Orthos Prime or Intel TAT.

Then one can judge about those values under full load.
