I see the Cooler Master NotePal U3 version has a variable-speed controller, but I don't see it on the U2. Is the U2 not variable speed?

That's correct - the U2 does not have a variable speed. Also, the U2 only has two fans while the U3 has three. I've had both - upgraded to the U3 after the fans on the U2 buggered out on me about a year after getting it - and I've been happy with it ever since. The variable speed is really nice to have it low when all I'm doing is browsing the internet / writing and then being able to turn it up when I play World of Warcraft. Hope that helps!

The company web site says that it will be comfortable on the lap."With efficient functions and superb silent concept in mind, the NotePal X2 creates optimal comfort for laptop users. Either on a desk or on the lap of an on-the-go user, the NotePal X2 takes air from a bottom intake and cools down high temperatures with its 140mm silent fans, dissipating the high temperatures generated by the CPU and GPU trapped inside the laptop housing." - http://www.coolermaster-usa.com/product.php?product_id=2936

The whole idea behind PWM (pulse width modulation) is so you can plug it in and forget about it because the bios or software takes control and adjusts fan or pump speeds for you. Anytime you see analog knobs on a device, that should let you know that you will have to manually control fan speeds on the fly or if the hardware has the ability, you can set max and min temps to dictate your fan speeds based on the temps you are getting from that particular temperature probe channel. Personally I like seeing temps and being able to manually adjust. Also I just like the look and feel of analog knobs on a potentiometer. Hope my point of view helps.

Everything I've read says you can't upgrade the RAM on the U120. I had just ordered it and haven't received it yet. I hope I won't regret not being able to add RAM. I researched as much as my mind could handle when I ordered this. I liked the light weight and the decent screen size and the brightness. It's all very confusing. Now there is a U120H. I don't know what the H has and why it's different. Better connectivity I've been told. Anyone know what this means? I don't want to have buyer's remorse. Sigh...it's all too much!

The V2 uses a 3-slot cooler design. The other DCII model is a 2-slot unit and rumor is that one is newer. The picture is correct and this is not a Matrix.

http://www.susanminor.org/Rayeimages/pid/diagram.jpgas mark said.the crux here is that in addition to the PID controller, you also need a thermocouple of the correct type, and for most applications, a solid state relay such as the one shown. the PID output relay is only rated at 3Amps. chances are you are going to want more than that.

This model is not variable speed but there are 2 speeds selectable via a switch on the top of the unit. It has High and Low speeds, 600rpm and 200rpm, respectively.

the 3rd gen i7 was known for running hot, however this is a 4th gen so i do not know. try 1 of these if u r concerned about heat, Cooler Master NotePal U3 - Laptop Cooling Pad with 3 Movable Fans by Cooler Master. Amazon sells it for around 30 bucks, mine works great, as far as noisy i dont even hear the 3 80mm cooler fans running and i have hyper hearing

I set my fan on max and then removed the chains from it as this controller works great at controlling the speed of the fan from low to high. It has 4 speeds instead of the 3 most fans come with.

I got the U31SD-XH51 with 2nd-Gen Intel iCore5 and a discrete nVidia GPU for heavy tasks (was on sale for $600USD) instead so I can't exactly tell you anything here. Mine runs extremely cool for browsing stuff and watching videos (fan doesn't even run at all unless I play 3D games). I also give credit to Asus for a well-designed cooling system on their laptop brand. Sources: I still own an HP-DV2210us model so I know exactly what you mean.

None, only at 100% fans speed (force set by after market software). You won't hear it under your CPU cooler - be it air or water cooling.

Hi Mr. James. I just got home to check out your predicament, and I can say that I arrived at close to the same conclusion. I set my fan to manually run at max and there is a visual disconnect though the Precision X HUD. The meter says my fan is running at max, but the digital readout on PX says it's only at 80%. That's not exactly what you're reading (75%)...but it looks like the same issue. For comparison sake I took the other fan software and did the same thing to see if I noticed the same issue.... and I did. For some reason all the Fan software I use say the max is 80%. What I found out after looking into it more was that EVGA apparently puts a limit on the max speed you can run their fans using external controllers. I do not know if the card itself will push the fans above 80%, but it seems that when using other software, that is the max. ...even so. Whether your fan is running at a true 75% top speed or the actual max speed, I find that my fan on max keeps things cooled to about 40-44c...which is well below maximum temps. Hope that helps! (on a side note, I've read that you want to keep these cards at 70c or cooler in order not to lose any clock speed. Supposedly, once they hit 70c the card throttles back the clock until temps are below 70)

Variable speed control. Very responsive and easy to use! It can be quite fast or very slow.

Hi Rustam, an excellent question! It had me puzzled for a wee while as well, but after a week of testing I can confirm that this is a dual BIOS card, and this switch switches from power saving mode (default) to uber mode. What lead to me discovering this switch was monitoring the card closely during BF4 sessions, and bench marking, and I could not get the card to use the full 1018mhz core speed. I used MSI afterburner and played with the power settings to the card, and found that @ +12-25% power boost, the card hits it's full speed all the time! ( Unless it hits 70c and throttles!). This switch does exactly what MSI Afterburner does using software, and pretty much lets you use the card to the full 1018mhz core speed, otherwise it will use 800-950mhz on both cores only. You can flick the switch at any stage, but settings only take effect on next boot. I hope this helps :)

I asked LEDwholesalers the same question RocPopy, This is there response."Hello:Sorry, our fans are unlikely to work with fan speed controllers.Regards,LEDwholesalers"That should clear things up for everyone.

The same switch-button that is used to select the speed is also the eject button when it is pushed. This could be an issue for some people since one might push down on the button in the process of selecting a speed. I haven't had any problem with it, however...

We did. We did not use a variable speed controller though. We set the fans to a high speed and then replaced the control with a simple on/off switch.
