OPOLAR Laptop Fan Cooler with Temperature Display, Rapid Cooling, Auto-Temp Detection, 13 Wind Speed(2600-5000RPM), Perfect for Gaming Laptop, Nintendo Switch

It applied and sealed properly it will decrease the temp significantly.Installed it on my cpu vent, max temp is 90 when turbo boost reaches 4 ghz, no more temp throttling at 95CThis is applied on asus rog STRIX scar IIIWill buy it again for ps4, and the other gpu wentFan noise is ok, high but not the annoying type, u can stand it as i am someone who hates noise and certain pitch noise

I just now got it from the Amazon guy looks like it's broken it's not turning on

Unable to be stuck properly on my laptop helios 300 so it doing just little

I started using this fan when I got it.I was super excited putting this on my MSI GS65. Unfortunately, It didn't benefit my laptop like it suppose it.As I was gaming, the fan continued to blow out air.As I was playing, i heard a loud screeching noise and I thought it was the fan. Once i turned off the two fans...I realized it was my laptop right fan that was not working properly anymore.I usually don't have issues playing games on my brand new laptop, but after two days using the fan, my right fan on my laptop didnt function anymore...My laptop is in warranty, but it cost me $47 to send it out to california to fix with a turn around time of three weeks...All I can concluded from this experience is...the fan didn't do its' job, because the end result was my internal fan didn't function properly after using the fan for two days...

Pros:~ The temperature display is very valuable.~ Fan is strong and fairly quiet.~ It is nice not having a bulky undercarriage but rather a side mount.~ It pulls air out of computer rather than the undercarriage types that push air into them. Pulling is superior.~ Multiple fan speeds provide customized control of both speed and volume level.~ It can be mounted with either suction cups or double-sided tape. The tape seems to bond strongly.Cons::~ Mounting instructions not thorough.~ There seems to be no way to get back to auto mode once manual is selected. Even after turning off and on again.~ Yet in manual mode after turning off it does not remember fan speed.~ In auto mode there is no way to adjust the default temperature target~ I would like the option to use electric outlet to reduce heat generation by loading USB port with fan current.Unknown:~ Durability and reliability are not known because I just installed it.~ Effectiveness of suction mount not known because I selected the other method.

Great item. Completely exceeded my expectations. Maybe one of my best purchases ever.I had serious doubts this thing would connect properly although I never doubted the idea nor the output of the fan. After about 10 minutes of playing around I figured out how to connect it with the right shroud, and the very ingenious slide on/off feature so you can quickly remove the entire unit if you have to thrown your laptop in the case and run out the door. Bottom line - take the time to connect this right and it works flawlessly, literally has breathed new life into my laptop which has a faulty stock fan. It literally 'blows' away any laptop cooling tray you could use.Highly recommend using the included 3M mounting tape which attaches the base place harness to the bottom of your laptop. This way, the fan apparatus slides right in and the shroud comes up to the laptop making a seal. Think of some space movie you've seen where they have to dock a shuttle with an larger mothership, and an airlock with seal comes and attaches to the craft. That is exactly what happens here for a nice airtight seal. The springy silicone shroud accomplishes this. The unit itself attaches to the base harness plate via a metal clip system which is also secure but easy on & off. Lastly there are two tiny arms that swing out (this perplexed me for the first few tries) but once you figure this out, it's the last secure step to stabilize the unit from the TOP of your laptop. This is the part you see atop, the two tiny gray arms that grip the side of your laptop near the keyboard. These work in tandem with the metal bracket out of view on the bottom.Here's the 'cool' part - when you need to take the unit off to stow your laptop in it's bag or head to the coffee shop or airport, the entire unit slides right off in 2 seconds leaving NOTHING on your laptop but the permanent tiny 3M harness which is on the bottom of your laptop but does not protrude or stick out in anyway. Therefore you'll have no problem storing your laptop or popping it into your laptop bag or sleeve. This is one incredible design feature and at first deterred me from buying because I didn't see this explained too well. Rest assured, the whole unit is completely and easily removable in seconds, and only takes about a half a minute to reinstall.Once its on and your laptop is running, it's up to you whether you run it in auto mode where it senses the temp or if you want to run it in manual mode and pick the speed yourself, but read on to learn some important differences between auto & manual.There is one major point here to note - if you are using this on a laptop with a broken stock fan, yes it will actually replace the need for a new onboard fan in most cases. You could never do this on a PC which can burn out a processor if overheating, but on most laptops the stock fan is routed in a series of venting pathways that simply vent to the outside where this unit attaches. By attaching this unit and having it on, it basically keeps great airflow going and I have never needed to replace my faulty fan and I use my laptop everyday (if there's ever a problem, the PC senses a possible overheat and hibernates or shuts down your PC well before damage occurs. I only know this because it happened a few times before I got the OPOLAR working and setup. Now it never happens. Anyway the reason I am taking the time to go into detail here is, if you have a laptop with a faulty fan and are buying this unit for this purpose, you HAVE TO RUN THE OPOLAR IN MANUAL mode from the moment you turn on your laptop and do so by kicking the speed up to at least 7 or 8 (pressing the speed buttons converts the unit to manual mode). Here's why: of you keep the unit in auto mode, it attempts to sense the temperature coming out of your laptop and will not suck enough air until it thinks your laptop is heating up and needs it. Well, if you have a faulty built-in fan that isn't blowing enough air, your laptop can overheat before the OPOLAR even knows it needs to start blowing faster, because the hot air is sitting in your laptop and not getting to the thermostat in the OPOLAR because your built in fan isn't moving the air! The solution for this is to run the OPOLAR in manual mode right away it gets the air moving immediately by pressing one of the speed buttons. Even with a faulty fan not running at all inside my computer, I can run my laptop normally with this amazing unit. Most people wont need to go through these steps, but if you have a bad fan and the repair shop tells you its going to cost as much as a new laptop to fix it due to it's location, then the OPOLAR is your best friend, and mine. This thing works WAY better than a cumbersome cooling tray. Also make sure you aren't blocking the bottom intake vents, and your laptop is sitting high enough off the table. I installed some extra rubber feet on mine to give it another 1/4 of lift so more air can get underneath to the air intake. Sometimes keeping the laptop on your pantlegs or a couch can totally block the bottom intake ports and no fan will keep your laptop cool if you make this mistake. If there's any small negative, it's that if you transport your laptop in and out of a case often, you'll need to remove and reattach the main cooler to the laptop each time. This is generally a quick process but it's a precise process of lining up the sleeve and slot, at times it's a little aggravating but not the fault of the product. Sometimes the metal plate disengages from the unit and I have to reattach it, I'm fixed this problem with a piece of electrical tape so it never comes off. A small price to pay for an excellent item. I like it so much I'm getting a spare.Totally amazing product and I have no relationship to the company. I just love great engineering and great products and this is one of those.
