I purchased 2 HP Laptop 14s-dq3026TU (50R74PA) Laptops that are passively cooled, (no fan)

Is it possible to purchase the fan assembly for this device? Does anyone know if the fan header pins are on the motherboard. One of them sits in a slightly warmer room and as soon as the processor gets hot enough, it throttles the cpu down to .40 Ghz and pretty much stops working. Why would HP build a device that only works properly in a well air conditioned room. Unfortunately I've had both of them long enough, that I can't take them back. Also I was unable to find a drop down that shows laptops, so that is why this is posted in the desktop section.

There is a service manual for the 14s here and it shows a fan.

You can try your serial number at the below site and look for a fan with a heat sink but I did not see any (heat sink) when guessing what you had

I think TW here is correct when he mentions the 14s probably uses the same chassis as the units with fans

You could take the system apart and compare to other 14-dq and possibly DIY some type of cooler.

IMHO, passive cooling means the CPU has a thermal connection  to the chassis to allow heat to dissipate.  All you need is to keep the chassis cool.  Get a laptop cooler for 14 inch chassis

Hi, @Jimmy-Rina 

Blame the hardware engineers from Intel that proclaimed several years ago that notebooks that come with Pentium and Celeron processors use such little wattage that they do not need cooling fans, which provides longer battery life.

I am pretty sure that there are no headers to add a fan in your notebook as they wouldn't be included on the system boards for those processors.

You couldn't just drop in a fan anyway since the notebooks with fans use different heat sinks as you can see in chapter 3 of the manual and no doubt the heat sink for the Intel core processors wouldn't line up with your notebook's system board components.

I agree with you since I have an HP Stream 11" notebook with an Intel Celeron N3450 quad core processor and after an hour or so of use, the thing gets pretty darn hot, and when it does, it slows down.

I recommend that you take BeemerBiker's suggestion and use some kind of laptop cooler if you can.

On my notebook, such a cooler would be fairly useless unless it could dissipate the heat coming out of the ventless case.

I've purchased two laptop coolers from K-Mart. I'm doing some testing with them at the moment to see how well they can wick the heat away. I'd like to thank both of you for your responses. I wasn't aware laptop coolers were a thing. I guess with a lot of passively cooled systems as well as high end gaming laptops, coolers are an essential item.

You're very welcome.
