KLIMTurbofrost Gaming Laptop Cooling Pad - 4 Powerful Turbo Fans - 4 x 4000 RPM, Laptop Cooler 2 Power Modes USB-C/DC, Dynamic RGB, 4-Ports USB, Sealed Foam for Fast Cooling - Up to 17in

I have a gaming laptop that is kinda showing it's age [MSI Crosshair 15 Rainbow Six - i9 12900H, Geforce RTX 3070, 64GB Ram, 2x Sabrent Rocket 4 M.2 SSD running Win 11].I was using KLIM Mistrel which I, regretably, damaged - it was 5 or so years old and a great little workhorse. I wanted a cooler that would be a good replacement for the old one.Enter the KLIM Turbofrost. I bought KLIM Turbofrost partly because I had seen some fair revues of it and partly because KLIM is a brand I trust - this is myfith Klim cooler [various laptops] and friends who got KLIM coolers on my advice are delighted with there coolers.The sales materials for this cooler on Amazon and elsewhere online are, as far as I can tell, acurate and truthful.Pros:Very easy to set upCan be powered via USB or wall outlet [adaptor included]Included USB 3 to USB C data / power cable for the 3 Port USB 3 Hub♠Sturdy constructionDraws air from underneath - no worries about possible intake of expelled warm airStrong adjustable hieght mechanismAluminium 'heatsink' plate [between laptop and cooler ventsPowerful fans with max 4000 RPM♣Adjustable foam 'riser' gives a great seal while letting excess air escape♥Metal restraints that help hold laptop in place [easily height adjustable]Multiple effect [or off] RGB lighting♦♠ At the rear; cooler has a USB Hub. The hub is not powered from the power in [wall outlet] power source but from a USB port on laptop. The included cable goes from a usb port of the latop to USB C of the hub thus providing power for the hub and data transfer. There are three [3] USB 3 ports. I have ran a usb lamp and USB Blu Ray from the hub at same tim with no issues. When not powered from wall outlet the USB C cable also powers the cooler.♣ When Powered from USB the laptop will use only 2 fans and reach a max 3300RPM not the max 4000RPM [needs outlet power]. However the 3300RPM will be good for many applications. In testing the cooling results [idle desktop] 12 to 13 degrees dropping by about 1 degree per step down [1500 gave about a 5-6 degree drop]. I used Hardware monitors and graphics / CPU stress testers and played Avowed, Atomfall, Startrek Online ane Elderscrolls Online all to test the cooling results. I did some video playback [USB Bluray], light video editing, audio editing, image editing and office task including '.pdf' work.♥ The foam is like 'memory foam' and provides a very good 'seal' between laptop and cooler while still allowing for air flow. The foam is held in place with four magnet [corners] and comes with a pre-cut detatchable piece - larger laptops = detatch piece - smaller laptops = leave piece in place.♦ I'm not fond of RGB effects so I either pick a colour and leave it solid or switch this feature off. There are several effecs to 'play with' - you do you!Cons:For me there are no cons as I find the KLIM Turbofrost ideal for my needs. However ther is two things that could cause issue;1 - This cooler is a beast! Although not too heavy the cooler is [to put it kindly] 'chunky'. Size can matter in a laptop cooler so keep this in mind.2 - Noise! I could not find my Db meter to monitor the sound. The cooler goes all the way to eleven so to put it! At 1500 RPM the cooler is very quiet but as the RPM increases so does the noise. Up to 3000 RPM the noise is not bad and not too distracting. If you go to 3500 RPM the cooler is fairly noisy but still not too bad. At 4000 RPM the noise [all 4 fans] is somewhat distracing and it is best to turn laptop audio up thus contributing to an 'all in all' quite loud experince that will likely get you ejected from the family room! Although it is not strictly needed, I would recomend using a good set of headphones, preferably with good noise canecelling, in a private room when gaming with the RPM at full power.The cooler is well packaged, has instruction manual and a quaint comic strip fold out included. There are also STICKERS! We all love a sticker!In a very good way the KLIM Turbofrost goes all the way to eleven! The cooler is competitavely priced and reviews well against more expansive brands or models.
