Acer Nitro 50 Motherboard

[Thunderace7]

Hi. I have bought a computer from ebay. It is in an Acer Nitro 50 case but was described as NOT being an Acer Nitro. I can find no manufacturer name on the motherboard but it is marked B66H6-AD which makes me believe it is the Acer motherboard that came with the case. It has an Intel Core i3-12100F processor, 16Gb of RAM and an AMD RX560 graphics card.
My question is regarding the chip shown circled in the attached picture. I believe this might be the PCH but should it have a heatsink on it? If so, what kind and where can I get one?
I have seen the PC working but I am reluctant to run it now in case the chip overheats.
Thanks.

Re: Acer Nitro 50 Motherboard

Looks like it should have, there's holes for the retention pegs to hold it....but just a quick google search of the board shows that it does not have/need a heatsink. Seems there are quite a few submodels of this board, but you'll get the idea.

^This, given that is a proprietary motherboard size/shape, and a proprietary power supply (sad to see Acer going this route, they were one of the last OEM pre-builts still using standard ATX/micro-ATX motherboards/PSUs), it is pretty certain that it is an Acer motherboard (it may or may not be original to that system). It certainly wouldn't hurt to add a heatsink (looks like the pretty standard "2 plastic push-pin" type) but it probably isn't necessary, though you may see some slight performance improvement with one if it is thermal-throttling.

Skipping the chipset heatsink is fairly common for OEM pre-built PCs, here's some examples.

Here's a Dell Opitplex 5060:

Re: Acer Nitro 50 Motherboard

Thank you both, that has put my mind at rest. I might still fit one if I can find one. I have found heatsinks for North/Southbridge chips but they are too big. There must be something to fit the holes but I cant find it. Maybe I'll just get a sticky one.
