    In my opinion, they are all pretty much the same, given that the heat is generated inside the case and they are only cooling the bottom of the outside?

    The main advantage to me is that they raise the laptop above the working surface and allow good airflow.

    I don't rate the USB ones, as they are using power from the machine and that generates heat. It also drains the battery.

    Increasing the RAM doesn't generate heat, only using it does.

    Your best move that you have suggested is to replace the HDD with SDD.

    Using an external drive as opposed to the hotswap would also reduce power demand and hence heat? Otherwise look at SSD, although I haven't seen 1TB yet, and it is expensive.
    If you cannot do someone any good: don't do them any harm....
    As long as you did this to one of these, the least of my little ones............you did it unto Me.

    the only problem im having with externals is they are designed soley for backup they arnt geared towards everyday use ive had 3 fail on me that way , thats why i was looking at getting a 1 tb magnetic for the hot swap port and a 200gb ssd for os drive just wanted to clarify i think i was half asleep before again thank you everyone so much for your help just wanted to clarify and share knowledge

    Hmmmm,

    I have an external HDD docking station. It measures 5"x3"x3" and will take 3.5" or 2.5" regular internal drives.

    About 2/3 of the drive is exposed when mounted, so is at ambient temperature. I could improve things a bit with a small desk fan.

    Basically, the enclosed external drives that I have seen don't have any cooling, so aren't really suitable for prolonged use?

    I guess I was asleep on my last post as well

    Obviously, if you are going to use the 1TB as a regular system drive you want it to perform, and a USB2 connected drive is only going to give you around 30MB/sec.

    The hot swap port must offer far better transfer rates than that? but I must admit I have never used one.

    I am looking to get a USB3 docking station which has to give me 60MB/sec, and will most likely be 100~200MBps, if external USB3 drives are anything to go by?.............my "fast" machines all have USB3 ports.

    Having said all that; if you just buy a 1TB drive and stick it in the hotswap port, just look at the temperatures. If you are having heat problems, you can always then go and buy a docking station and stick the very same drive in that.
    If you cannot do someone any good: don't do them any harm....

    For whatever it's worth; The one I bought has a little "Heat Sink" lol, built into it, and then two fans, keeping the air flow.

    Nihil has a point though; Anything you hook up to the machine itself, is going to in general, raise the temp.

    And Spec basically said exactly what I do; Take a Vacuum, and just suck it like you owe it money. That way you don't have any dust bunnies. Ohh I made a rhyme! lol.

    Where is the air intake?

    Have you blown out the air channels with canned air?
    When was the laptop opened up and the dust bunnies and junk cleaned out?

    When Cnet tested cooling pads http://news.cnet.com/8301-17938_105-9700… out of the 8 they checked out, the one without any fans cooled the best http://reviews.cnet.com/docks-stands/xpa… the XPad.

    In your case, you *might* want to consider having the unit actually taken apart periodically. Why? Are you familiar with how a clothes dryer works? You know the lint trap? You know how after one use, there is enough lint on that screen to form a layer thick enough to peel off in a single pull? Well... the fan in your laptop sits in front of a heat sink. That heat sink is a piece of copper or aluminum, cut so that there are parallel fins that the fan pushes air between. The leading edge of that heat sink catches debris over time... and the more debris that is caught, the more that *debris* catches even more debris, until you get a layer of material between the fan and the heat sink. This will obviously impede the flow of air in the cooling channel.

    This happens to EVERY laptop... and it happens in as little as 2 months in some environmental conditions, and it can take 6 to 8 months to get really bad in other situations. So, I can't tell you how often it will happen to you. What I can say, is that if you have never had that cooling channel cleaned, and the unit is at least a year old, then there *IS* a layer of that dust/debris between the fan and the heat sink within your laptop.

    Some laptops have a panel over the fan, where you can simply remove this panel and then you are able to service the fan easily. Other laptops require you to completely disassemble the unit to the point of removing the motherboard to get at the fan and heat sink assembly. I have no idea the make and model of your laptop, so I can't say whether it will be easy or not for you.

    What I am saying though, is that before you try chill pads or clip-on fans... you might want to consider simply cleaning the laptop.
