So I recently put together a new build, significantly more modest than originally planned due to car troubles that ended up costing a lot of money. Anyway, I got a 4770k and a silverstone tundra TD02 240mm AIO CPU cooler, I read the reviews on it which were all positive and since I was going for a white and yellow/gold theme it fit perfectly. Installation was fine and everything runs smoothly when on the desktop or doing general tasks. The problem lies in gaming, which is what I put the machine together for. The tundra is controlled by motherboard fan controls, I have the MSI z87 mpower board and it does choose fan speeds pretty optimally, but after gaming for a short while (and temps rising) the fans get to a certain RPM (around 1600-1800) that cause everything from my case to my entire desk to shake uncontrollably. and by uncontrollably I mean gaming becomes impossible because my mouse moves erratically by itself. Below this "sweet spot" is absolutely fine, even above it to max (2400 RPM) is fine. I tried anti vibration gaskets between the rad and case (didn't have enough for fan to rad) but it didn't have any noticeable effect. My questions are many: Is this normal or have I got a malfunctioning unit? What are my options? Should I just be setting the fan speed to max before gaming and deal with the excessive sound of the unit at full speed? Will full anti-vibration fan pads on both the rad mount and fan mounts make a difference? Are there any other ways I can control the vibration? Case: NZXT H440 (at first I thought the limited exhaust ventilation was to blame, rad is mounted up top, but I took the top off completely and vibration continued.) GPU: Palit Jetstream 780ti (I ramped this up to 100% manually to make sure it wasn't the problem and it isn't) Edit: I forgot to mention that the supplied MSI command centre program only allows me to manually set fan speeds to 25, 50, 75 and 100% and the 75% appears bugged because it just ramps up to full. Speed fan mustn't support my mobo which has 2 CPU fan inputs and will not let me control the CPU2 fan which the fans are plugged into (pump plugged into 1). Are there alternative programs I can look at?
