5 out of 5 eggsGet This!

Pros: Versatile fan placement, light weight, sturdy and great angle to work on laptop. Fans are extremely quiet and quite large. Speed control is a nice feature.

Cons: Might need to be careful when mounting and dismounting the fans since they have plastic brackets for holstering into the metal grid. A nice release button helps to avoid any stress to them though. Also, avoid putting too much stress on the wire housing into the fans. This might cause a broken solder inside.

Other Thoughts: I just got this for my "beast" 17 inch Macbook Pro. Heat has always been an issue and getting proper circulation underneath to keep it cool has been a challenge. After exhausting every option, I bought this cooling pad hoping it would be my answer. It was! This is one of the best purchases I have made in a long time. This thing is built extremely well. Grips keep my monster in place, the carrying feature is awesome and the fans are extremely quiet while keeping my Macbook nice and cool. Hats off to the makers of this product, they know what they are doing and no more shut downs from overheating! Look no further for your laptop staying ventilated and visually appealing as well!

3 out of 5 eggsShould have held out for a U3 Plus

Pros: Fits my MSI GT70 17" laptop perfectly
Quiet - almost silent at high speed
Great design - no tools required to relocate fans

Cons: Airflow not what I hoped for

Other Thoughts: I was looking for something to help me avoid using the "Turbo2" fan function on my MSI GT70 (it's LOUD). I should have looked closer at the U3 Plus, but unfortunately, the U3 Plus is out of stock, and the U3 was on sale plus there's a mail-in rebate.
If there was more airflow, I would have given it 5 stars - great design!

3 out of 5 eggsIt's okay

Pros: Modular fan design
Wider than my laptop (17" Dell Inspiron)
Pass through USB port
Quiet fans
Good price (after rebate)

Cons: Doesn't move enough air

Other Thoughts: I decided it was time to buy a cooling pad because I noticed that my laptop fan was cycling more and more often (even after cleaning). I settled on the NotePal U3 pad because of the modular fan placement and the fact that the physical dimensions of the pad are larger than my 17" Dell Inspiron. I haven't had any problems with the laptop moving feels solid on the stand. However, when monitoring my CPU temp there is no noticeable difference when the pad is running as versus when it is off...CPU regularly exceeds 60°C. At least it was a reasonable price.

Manufacturer Response:

Dear Customer,

We are sorry to hear you had trouble with our cooler. To clarify, you won't see a considerable difference in the cpu as the laptop cooler is not a cpu cooler, it is a laptop cooler, meaning it will cool your entire laptop as whole, providing fresh air into the vents on the bottom of your laptop. May we ask, did you check your system or hard drive temperature as well (before and after use of the cooler)? Most likely, you will bigger changes there than the cpu cooler. If you wish to troubleshoot further, please contact us so we can be of assistance.

5 out of 5 eggsUseful

Pros: All 3 fans are very quiet. Being adjustable also helps to concentrate the air flow. About half a year of daily use for a gaming laptop and the thing still hasn't fallen apart!

Cons: One of the fans is making slightly more noise than before, likely due to its screws becoming a little loose. Not a big deal, since the fans can be taken apart to be cleaned.

I guess if you really want something portable, the frame and fans might seem a bit too flimsy for rugged use. Best to just leave this thing at home and don't drag it around everywhere.

Other Thoughts: I'm wondering how long it will last. The fans dying eventually is to be expected, but good track record so far tho.

2 out of 5 eggs

Pros: Sturdy and I like how you can configure the fans where all the heat is outputting. That's the main reason why I bought this product.

Cons: A little after 2 months my fans just stopped spinning. If you blow on the fan to get it started, then it will start spinning again. Not sure why I even have to do that, but I'm not happy with this product.

4 out of 5 eggsGreat, but missing a key feature

Pros: It is relatively sturdy for my 14" Lenovo Y40 and I love the custom placement of the fans. Given the location of my laptop's hotspots and vents, I think a single 200mm+ fan would have actually missed them. The reason is that with bigger fans comes bigger gaps of airflow. Fans do not have even distribution of airflow up close. Having smaller fans has allowed not only custom placement, but has provided more concentrated airflow to key spots of the laptop.

Cons: The fan controller seems a bit flimsy and there is a lack of extra usb ports.

Other Thoughts: The lack of usb was huge for me. Many laptops have only 3 usb ports and would be nice to get a couple of extra for low-power peripherals. I would not want to plug my usb-powered headset into the pass-through of the cooling pad - there is too much competition one port between the fans and headset.

4 out of 5 eggsLove the Adjustable fanspeeds

Pros: -Quiet
-Light weight
-Well made
-Adjustable fan speeds and positions
-Good Fans
-Doesn't tax battery life as much as others

Cons: A little bulky. I can't fit it in my laptop backpack. I have a 17.3 inch that just makes it into the bag. This cooler just can't travel with me well.
