Cooler Master NotePal U3 PLUS Laptop Cooler - 3 Moveable 80 mm Fans, Carry Case Protector, Ergonomic Aluminium Frame - Black

Having decided to use a Dell Latitude with i7 processor, I discovered that these babies burn hot, very hot. This coolmaster pad contains two easily adjustable pads which can be moved to match the intake area on the bottom of your laptop. Having the laptop off the desk also allows for some increased airflow. The two fans are not very strong, but they definitely DO move some air. I find that with the fans operating my laptop's CPU temperature is reduced by about 5 to 8 degrees C. Given that there is an enclosed dual exhaust within the laptop I wouldn't have expected it to have that much effect. Other components may benefit more. That will hopefully be good for it long-term. The pad looks attractive. A bit of 'bounce' exists if one is typing hard, but I personally do not find this to be a problem. An advantage is that there are no LED lights etc which many of the pads seem to have to attract the gamer market. That is fine, but I use my laptop primarily for business. The pad is suitable for laptops up to 15" max. My Dell is 14" and I think it is the ideal size for this cooling pad. Anything with a screen greater than 15" is likely to have excessive overhang and the fans may not reach where they are supposed to. The fans are not silent but I do not think they are so loud as to be distracting. Each to her own where noise is concerned. It would be straightforward to fix quieter or more powerful fans if you wished. My son has pointed out that I could fix some spare powerful fans taken from his gaming desktop case which can be converted with a £1 socket (from amazon) to be inserted into a USB. The fans do not have to be used at all if you need quiet - just take out the usb. Hope that helps!

Great laptop stand. Easily fits my Asus ROG 17" laptop. In fact is has a little room to spare. The fans that come with the stand are not that great I dissembled them and tried some Loctite super lube (from the little 7g pen as lighter grade oil than bigger bottles). There was an improvement but still nothing to write home about. I decided to upgrade the fans and today I received the bits I ordered to create a fan rig. Unfortunately I followed the specs of a Youtube guy who also did a fan build. He used the Noctua NF-F12 iPPC 3000 PWM, Heavy Duty Cooling Fan. They do deliver loads of air but sound so loud, like the old Dover to Calais hovercraft. I sent them back in substitute for the Noctua quite fans, not as much air but so much quieter. The rig is really easy to make and the parts are all available on Amazon. Especially with the speed controller I found, with a cheap 12V adaptor (power source) it is just a case of cutting the ends of stripping some of the jacket off to give you a little flex/wire, poke the ends in to the appropriate controller hole and tighten the screws (= & - diagram is on bottom of the controller). Links for them are below. I did go with the cheapest power source/adaptor. I will upgrade but just wanted to go cheap to see if it all worked ok. If you buy the Noctua quite fans they come with rubber mount clips and splitter cables. The industrial ones do not. The industrial fans will likely cool even the hottest laptop, as they deliver serious air but even headphones do nothing to dampen the noise. The Noctua quite fans are much more powerful than the standard fans. https://www.amazon.co.uk/gp/product/B084QB29TG/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 https://www.amazon.co.uk/gp/product/B08J3W6M9G/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1 https://www.amazon.co.uk/Noctua-NF-F12-PWM-Premium-Quiet/dp/B00650P2ZC/ref=pd_sbs_3?pd_rd_w=2E8OY&pf_rd_p=2304238d-df78-4b25-a9a0-b27dc7bd722e&pf_rd_r=HY6FN3PS6ZRM1P96G29H&pd_rd_r=64ee0f96-d78d-4fce-9005-f98e1ffd7f9f&pd_rd_wg=tobnP&pd_rd_i=B00650P2ZC&psc=1

Excellent laptop cooler. The adjustable fan positioning means you can get the airflow exactly where your laptop gets warm, or where the airvents are. It has a big range of fan speeds on a smooth speed dial (not position 1,2 etc - the dial rolls around to exactly where you want) and it's pretty quiet on the slowest one, quieter than if the laptop fan comes on. On high it does sound like a desk fan going! I've not tried gaming with it yet, but for regular use the laptop fan never comes on with the cooler on the slowest setting. For size, it's a perfect fit for my 15.6" Lenovo Thinkpad P50. The laptop fits just within the metal grille, with the frame around it. A bigger laptop would seem balanced on top of the cooler. If the airvents were on the edges the main airflow zone wouldn't be in the right place to do much good. It would also be really awkward if the rubber feet were off the grille for a bigger laptop - you want that height for the airflow, and it wants to slide around a bit as it is. I'm not an expert, but it makes sense to me that the laptop isn't sticking out off the edge of the cooler. So I'd say perfect for 15.6", fully within the airflow grille. 17" should sit with the feet nicely on the frame around the grille, but I don't see how it would work for a 19" machine. There is one really odd feature, which is why I knocked off a star from 5*. If I leave it plugged in and switch the computer on, it doesn't come on when the laptop is switched on, then when I switch the laptop off the cooler fan starts working! (If laptop mains power lead is plugged in.) It starts up immediately if it's unplugged and I put the USB lead in. The way round this is that every time I switch the laptop on, I turn the cooler fan speed dial up and the fan comes on, then I can turn it down to minimum speed again. It's a bit of a nuisance, having to remember to switch it on in that way each time. But I don't mind too much, it's still decent equipment and I like it.

Went through about 4 stands so far with various issues including 3 that outright lied about "suitable for 17" displays" and one that the build quality was that bad it had partially disassembled a rest in transit slicing the power cable. Enter the CM U3+. Construction: Aluminium and Vulcanised Rubber. Solid but lightweight, well finished and obviously went past QC. Stand : Nice finish, light, stable and ergonomic. First one to actually take the 17" TUF705 with clearance vs the others including the one that wouldn't even take a 14" dellbook without overlap never mind the ASUS. Fans : Almost silent, easy to fit and move, noticeable smooth airflow no matter where placed. Operation : Does what was needed. Consistent 6c on low end and 3c on full "stress" operation levels on the CPU, less extreme but still good reduction on dGPU. Might not seem much to some folk but for a laptop that's pretty helpful and an extra safety margin on the thermals. All in all, the one I wish I'd known about at the start so I could have saved a pile of time.

ABSTRACT: Tested the CM U3 in multiple cases. Using the cooling pad without the fans reduces the temps the same as using a book to raise the laptop (~86c to ~82c). Using the oringinal fans and even extra fans for better effect doesnst reduce the temps in this case (high CPU Usage) but reduces the internal fan speed and subsequently the noise (Full to High). INTRODUCTION: I did some benchmarking with this cooling pad. I tried multiple cases to test the temperature difference with and without the CM-U3. I also used extra 2x120mm fans made by Eluteng, each one of 56CFM. The fans were targeting the two entry holes of the laptop that are found at the bottom side. The different cases are listed below (Not the same as the test number) Different cases tested: 1) Without a cooling pad 2) Raised computer with a book 3) With the cooling pad and no fans 4) With the cooling pad and 3x Original fans -> 45 CFM 5) With the cooling pad and 2x120mm fans (Eluteng) -> 112 CFM 6) With the cooling pad and 3x Original fans + 2x120mm fans (Eluteng) -> 157 CFM EXPERIMENTAL RESULTS: + IN GAME TEST: Test A1-A7 Max CPU Usage= 70-100% Total CPU Usage= 20-50% GPU Usage= 65% - Test A1: In game Case= None External fans= None Internal fan speed= FULL Average CPU Package= 86c GPU Temp= 79c (Not accurate) - Test A2: In game Case= Book External fans= None Internal fan speed= FULL Average CPU Package= 80c GPU Temp= 72c (Not accurate) - Test A3: In game Case= CoolerMaster U3 External fans= None Internal fan speed= FULL Average CPU Package= 81c GPU Temp= 73c (Not accurate) - Test A4: In game Case= CoolerMaster U3 External fans= 5 - But None active - CFM= 0 Internal fan speed= FULL Average CPU Package= 83c GPU Temp= 73c (Not accurate) - Test A5: In game Case= CoolerMaster U3 External fans= 3 - 3xOriginal CM Fans - CFM= 45 Internal fan speed= High Average CPU Package= 82c GPU Temp= 73c (Not accurate) - Test A6: In game Case= CoolerMaster U3 External fans= 2 - 2x120mm Fans Eluteng - CFM= 112 Internal fan speed= High Average CPU Package= 83c GPU Temp= 73c (Not accurate) - Test A7: In game Case= CoolerMaster U3 External fans= 5 - 3xOriginal CM Fans + 2x120mm Fans Eluteng - CFM= 167 Internal fan speed= High Average CPU Package= 83c GPU Temp= 73c (Not accurate) + TORTURE CHECK: Test B1-B5 CPU Usage= 100% GPU Usage= 100% RAM Usage= 95% - Test B1: Torture test Case= None External fans= None Internal fan speed= FULL Average CPU Package= 93c - Test B2: Torture test Case= Book External fans= None Internal fan speed= FULL Average CPU Package= 92c - Test B3: Torture test Case= CoolerMaster U3 External fans= None Internal fan speed= FULL Average CPU Package= 92c - Test B4: Torture test Case= CoolerMaster U3 External fans= 3 - 3xOriginal fans - CFM= 45 Internal fan speed= FULL Average CPU Package= 92c - Test B5: Torture test Case= CoolerMaster U3 External fans= 2 - 2x120mm Fans Eluteng - CFM= 112 Internal fan speed= FULL Average CPU Package= 92c CONCLUSION: The materials and the sturdiness of the specific cooling pad are extremely good. But other than that the cooling effect is lackluster. There is a reduction in temps with the cooling pad without fans and the book but they are almost the same. The temps with the fans active dont reduce temps but reduces the internal fan speed from full to high. In other words, using a book to raise the laptop height reduces the temps the same as using the cooling pad without the fans. By using the fans you reduce the noise from the internal fans by one level. Keep in mind that the test used a game that kept one CPU core at around 70-100% while the average was 20-50%. Thus, it was causing some additional preassure without using too much energy (not energy throttling). A game with a smaller Max CPU ussage and better allocation of resources would have a better results but i dont expect large difference. Additionally, other cooling pads are expected to have the similar results in tough CPU tests since extra, strong fans were used. Now judge for yourselves if you believe the price is worth it. Maybe using an external power source for even stronger fans would offer some additional cooling.

The detachable fans fall at the slightest shake. Not usable on lap, they always fall. On a desk they might be ok. Also, the fans have some pins, that stick out too much, and the laptop sits on them, and gets scratched beneath. Not suitable for MacBooks as they have short feet, and the bottom of the laptop sits on those fan clamps/pins. Also, is too big for MacBook Pro 16 2019. The cooling is good, but is not reliable for my use. Have to add that the product was sent in the original box, with amazon label on it, and the box was open, but nothing was missing,

I purchased this on the recommendation of a Dell laptop engineer. As a professional photographer I’m running a VERY high spec XPS15 for photo editing - often exporting large batches of files from RAW originals. To me workflow speed is everything so keeping the processor working at its optimum is key. For all their benefits, the latest generation of thin, lightweight and mobile laptops still struggle with sufficient cooling. The ability to customise the positioning of the fans has allowed me to place two I’ve the fan intake vents under the machine and one directly under the processor - all this coupled with the fact the laptop no longer sits directly on the table top but has room all round to “breathe”. Construction is sturdy and impressive. I was unsure cow the angled keyboard would suit me but it’s been a cinch to get used to and is very comfortable. There is ample space around the XPS15 (and my old HP Spectre 15) and it’s clear it would easily take the XPS17. I’m so impressed I’m going to purchase the smaller 2 fan version to take on location shoots.

Use this with my HP Pavillion G7 17" and it is very good at reducing the core temp quickly. I use the laptop for gaming and editing and the cooler master means I can work/play for longer without worrying about overheating. I monitored the temps over a week with/without the fans and the difference was incredible: 60-70 degrees Celsius minimum without the tray and 35-45 degrees Celsius with it. The aluminium frame dissipates heat quickly and the fans themselves are powerful, without being especially loud. The rubber grips have not detached or frayed at all in 3.5 years of solid use and the fan clips also still give the same performance, holding the fans tightly against the tray and preventing vibration. They're very easy to adjust or remove, and also easy to clean. This product is fantastic at what it does and for a very decent price, couldn't be happier.
