  1. Fans included stock with radiators are normally designed for high static pressure - so you should mount them in a "push" configuration.  Adding a "pull" fan should help in most instances, but your call if you want to spend the extra $ and deal with a little bit more noise.  Same with replacing fans - there are better fans out there, but it comes down with the money you want to spend.  Out of the box, stock - the Seidons do a good enough job for normal duty and decent overclocks.


    I echo the pump comment made by Heng KengYan - the pumps should be connected to a constant, full speed PWM signal from a four-pin header.

  2. I had a similar problem with my Seidon 240M, but with the pump just being inoperative (it's going thru the RMA process - hurry, CM! :happy7:).  I DID not have any noise, however.  For the OP, I would consider RMA'ing the cooler.


    Ntua - the CPU_OPT header typically provides full PWM signal, so your pump should be running full speed.  You state you have a "similar problem", but show the pump running at 1800rpm.  Has the pump stopped working in the past?

  3. In terms of cooling - it's a wash: both configurations should yield comparable results.


    Two other considerations: noise and dust.


    The 200mm fan will spin slower and in theory, be quieter.  If you're going to have this tower on your desk - put the big fan on the front.  Otherwise, put it on the top if the case is going on the floor.


    Additionally - do you want a positive pressure or negative pressure case?  Do the front airvents have filters?  If so, mounting the two 120mm fans in the front with an air filter should ensure positive pressure and minimize dust buildup in the case.  If it's negative pressure - (i.e., smaller fans exhaust, larger fan push), dust will get into all the air openings of the case.


    Both above points are dependent on how your motherboard controls fan speed - depending on how each of the two types of fans react to variable speed may change the situation.

  4. Not familiar with the Hyper 612, but with the size of screws typically used for mounting brackets and the weights (even this heavy thing) of the heatsinks - the screw should be enough to hold the heatsink in place when fully torqued down.


    Hate to ask the obvious question - you have the correct screw on the heatsink and torqueing down to the matching sized thumbscrew/standoff on the bracket?

  5. At that frequency, you should go water cooling - air cooling most likely will not be enough.


    The 240 will fit - a quick search on Google shows an image of what looks like a Seidon 240M easily installed on the top dual fan mounts of the case.

  6. I have seen many Hyper 212's mounted on mobo's in tower cases; as far as I can tell, there hasn't been any problems.  The backplate should be able to distribute the load to prevent it from having a problem.


    Other than switching to the 101, which you say isn't available - you best check with CM, or even with Gigabyte.  You should be fine with the 103; have the manufacturers confirm.  Good luck!

  7. That case looks standard width, so I'd imagine any of the Hyper series coolers will fit.  If you check on each of the coolers on this site, it will give you a height measurement.  For example, the Hyper D92 is 145mm tall - and that one looks like the biggest.


    As for weight - air coolers are typically copper core/heatpipe/aluminum fins - so I think you would be hard pressed to hit a 450g limit (the D92 is a little below, at 448g).  I'd ensure you have a cooler with a backplate mounting scheme, which looks the case of all the Hyper series with the exception of the TX3 EVO.

  8. On my ASUS ROG motherboard, the cpu_fan header varies speed by cpu temp.  The cpu_opt maintains constant voltage.  I would swap them - the pump should be running full speed (it should be quiet, despite the rpm) - make sure the pump rpm shows 1400 rpm or so (at least that's what my Seidon did).  The radiator fans should be hooked up to the cpu_fan header, so it ramps up the speed according to cpu load.  Do you have the fan speed profiles set up in BIOS?


    As for your temps, several questions:

    - Are you overclocked?

    - Is your ambient room temp much over 24deg C?

    - Not familiar with the Intel tuning utility - does it vary clock speed and voltages?


    For my old 2600 i7, at stock voltages, stock speeds - 100% CPU utilization, I was around low 50's with 24deg ambient.  So your 80+ temps seem rather high.


    Per previous discussion, if your pump isn't running full speed - that is most likely the culprit.  Swap those fan headers.
