CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E39 M5/540i running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in our wind-tunnel lab.This Part Fits:

Great item!
works great. I can plug my backup into it and my printer, so I don't need to connect the printer to the internet.

Great in every facet
Color: Space grey
This thing works well. No complaints at all. haven't had any problems with heat, and it fits into your pocket but doesn't fill it up. This is a great value, especially if it's on sale and you need extra ports or an sd card reader or both I would encourage people to try it out!

This hub worked when others did not
Color: Pink, Color: Pink
I have an Asus Zenbook that's at least 7 years old (ancient by technology standards) and it has a very problematic USB hub. I love my laptop. It functions well except for the hub. I usually get OEM peripherals for my electronics. (I use PC and Android. I'm not a Mac/Apple user.)
In the case of the USB hub for my Zenbook the Asus replacement hub is garbage with a 1 star review on Asus website with warnings not to buy because of how fast it stops working. The Asus hub I purchased 3 months ago stopped working after using it 3 or 4 times. That's unacceptable in my opinion. I have tried other brands including Belkin, Anker and 2 others that I do not remember. None of them would deliver power to my laptop despite claiming they would. So I decided to try this hub. I need an external hub for the multiple USB ports because the Asus has no ports on the Zenbook itself, and power delivery (in a perfect world when everything works properly) should also be able to go thru the hub to charge the laptop. On my laptop, there's only one USB-C port to connect either direct power supply or a hub. You can't have both connected at the same time unless the hub allows power transfer to laptop, which the other brand hubs that I tried wouldn't support that power transfer, much to my frustration. This hub is the first hub that I've tried that will actually power my laptop. (I also switched my power supply cable to a Thunderbolt, so the combination of the new cable with this hub works.)
I use a wireless mouse with a dongle that needs to be plugged in. I have a digital voice recorder that plugs in directly via USB-A to transfer files to the laptop. I use SD cards in my camera and MP3 player that I need a hub to transfer that media onto the laptop. This hub will allow all of that. Every port works that I have tried on this Acer hub and this hub does the thing that the other hubs failed to do on my laptop. The power transfer was the big issue for me and this Acer hub solved the problem that several others including the OEM, Asus, failed to do. Because of how many months I have been dealing with the power supply problem, hubs not delivering what they promised and this being the only hub that did work, I rate this product at 5 stars. It's less expensive than the Asus hub that stops working immediately after purchasing. It has more ports than the Asus hub with the extra SD card reader that the Asus hub doesn't have. It's a heavier duty outer shell compared to the Asus. The cord is thicker and better protected compared to the Asus, so it reduces the chance for stressing or bending the cord in a way that could break the wires inside or break the connector away from the wires. It's just a better design overall, when compared to the Asus hub. I am extremely satisfied with this Acer hub and I would recommend it since it did the "impossible" task that no other brand could do for me. 5 stars, indeed.

Actually amazing hub, it just works!
Color: Space grey
This dock is carrying my handheld system so hard right now, and for such a good price. I have literally every port filled including using the HDMI and it hasn't failed on me at all.
