Question: Is the air flow on hands on the X3 a must-have feature?  The X3 looks quite a bit bulkier with it than the X2, but maybe it's just the photos.
Document: My laptop heats up quite a bit, especially when I'm doing graphics intensive stuff. This did exactly what it was supposed to do and cools it down well. It is a bit bulkier than other laptop cooling pads, particularly because I use the little feet on the bottom to allow even better air flow, but I have had much less overheating issues since starting to use it.
I have similar fans in my desktop case and are very quiet when on high speed. But, the fan does move quite a bit of air and helps aid laptop cooling.What they could add-on to this product is maybe some rubber feet/squares that you can put on yourself on top of the cooling pad.
This might not cool the laptop properly or hold the laptop well.Cooler Master NotePal X3+ 200mm fan is very big, so cooling performance is good with lots of airflow+ has cable management design underneath the pad- It's about $12-14 more than X2, and it looks more bulky.
I bought this fan for my new computer, it really did not have any heating issues but anyways I wanted it to keep my computer running cool, I thought this would be a little bit better regarding the fan speed, even on the max speed it is a little bit slow, also my computer slides a little bit, maybe because of my computer's anti-sliding pads but the product could come with some kind of anti-sliding feature.
I bought this brand of cooling pad because it looked very sturdy and seems like it could do the job. I had it so far 4 months and and it is still standing up to the test of me using my laptop constantly. Another great feature is you know when it is on because the blue light illuminates the cooling pad. It has a control knob that lets you turn up the flow of air to your liking.
Help reduce heat and extend the service life of your laptop. After reading several reviews, and having two other laptop cooling systems fail, decided to try this one. One of my best investments in sustaining my laptops. Good amount of air flow, adjustable speed control excellent option, and my laptop internal fan is louder than this fan. The quality, this unit is well made, feels solid compared to several other coolers I've owned. The blue LED light is nice feature especially at night.
I bought this product in hopes that it would cool down my laptop's overall temperature and take the pressure off of my internal fan, and it did just that. Extremely quiet run speeds, and it's handy that this model has a fan speed control wheel so you can adjust the amount of air flow for your specific needs. I usually keep it about 1/3 of the way for normal use, and maybe a 1/2 to 2/3 speed for gaming.
I have a Dell XPS M1130 that is getting older now and gets very very hot. A criticism that I and other friends have about Dell laptops is that they heat up quite a bit and I'm not sure if I'll get one again in the future because of this - but maybe they've improved.
I have had many laptop coolers which have disappointed. I love the Cooler Master NotePal X2. The fan is quiet but powerful. The top surface (which is not easily seen in photos) is mesh. This allows the fan to cool any area of your computer that is venting hot air. So far, so great.
It does an OK job for the price. Allows better air flow to help prevent overheating. May only reduce temp by a few degrees but every little bit helps sometimes.
Answer: The air flow on the hands is by no means a must have feature.  With the X2, the surface of the laptop keyboard is cool enough that my hand aren't noticing any heat difference.  The larger fan of the X3 will cool your laptop a little bit more, but in my opinion not worth double the price of the X2.
