Can I damage the nitro 5's cooling fan inside using an external fan?

Hello
So, I just did a DIY PVC pipe laptop stand with an external fan (220V) that is directed to a type A AC power socket.

Since I got a powerful external fan, I was wondering if I can damage the nitro 5's laptop fan with an external fan underneath?. It has a 2 cm gap from the laptop's air intake to the external fan. The external fan is usually not that big though (12x12x4 cm). And yes it is loud and it does vibrate since I only used cable ties to mount the external fan to the DIY Laptop stand. I just hope it won't damage some internal hardwares. 

Anyway thank you in advance for the answers.

    I don't think it can incur in any problem, I would secure that fan though so that it doesn't vibrate to have less noise, but given its dimensions I don't think it can push enough air to be a problem.

    There are ready made coolers that use even 14 cm fans, although they do go slower because their aim is to be more silent than those coolers with 8 cm fans.

    I'm curious though, why the 220v? Where did that fan come from :D ? Or are you using some sort or transformer to bring down that voltage.

    Hello thank you for your answer. The normal vibrate part of the external fan is not a bad thing right? I remember someone said in our FB Nitro group that vibration is bad for the HDD, I'm not sure what is the relationship of the vibration to the HDD though.

    I got this external fan from online and I don't know where is this exactly use for. My first plan was to invest a dual 12v external fan but all I can find are PC system unit cooling fans which they are connected to the motherboard or power supply. And I just changed my mind to just invest a 220v fan connected to a Type A AC power plug, since I only need an external fan for my laptop.

    HDDs and vibration are not friends, that's for sure. I can't tell you specifics, but think that inside of an HDD there are disks spinning at great speed (some 5400 times per minute, others 7200 and some even more). In between those disks is there the reading/writing heads are, think of them as some sticks that move along the disk surface to read and write in different parts.

    Disks are designed to withstand some vibration, but they're not keen on it, if they're strong enough they could cause the heads to bump against the disks causing damage for example, or you could see their performance degraded. So yep, typical notebook grade hard drives aren't as resilient to vibration as others like NAS drives because they're often stacked together.

    But I don't know how much of a vibration that fan produces or its effects, it may be meaningless for the disk for all I know. Plus, vibration is not one of the things listed in specs of the disks, you can see shock resistance for example, but not vibration effects. There ought to be some blog posts about the matter at least, the net is vast and (sorta) infinite after all.

    I was curious about the fan because I'd rather not have live AC near my working place or my legs if I have the cooler over me haha, make sure every connection is isolated properly.

    Oh I see, thank you for that information. 

    The 220V external fan is plugged in to an AVR (220V socket) together with an on/off switch adapter just so I can just turn it on/off easily without plugging it out on the AVR. I wonder if this is a good idea? Since here in the Philippines, Blackout occurs often here and faulty voltage (flickering lights). I'm not sure what is the actual term for that LOL.

    About the vibration part, I did a little bit of research that rubber pads can help vibrations. Luckily, I already installed some rubber pads. Not for the vibration but for the paint that sprayed on the PVC pipe 😅. But I guess the rubber pads have a new purpose.
