I'm going to be building a PC in a few years and I'm already choosing the parts for it. Are 4 58 CFM fans enough for a Ryzen 5 3400G CPU and MSI 1660 ti Ventus XS 6GB OC GPU?

Things always change in a few years time, so this is a question better left answered at that time. I'm not sure why you would select a CPU today to build in several years as unless you have a time machine, you don't know what your options would be.

That said, four case fans are overkill for just about every build out there. Many pre-built PCs like Dell and HP typically come with one case fan.

Do you mean 4 total fans (besides the one on the video card), or 4 case fans? That setup doesn't need 4 case fans.

4 total fans is just right, if speed controlled, and one is in PSU, one on CPU 'sink, one on case rear wall so CPU heat exits instead of going through the PSU, and one front intake to help create positive case pressurization for a filtered intake, and help cool HDDs if present, then you can block off the unused fan mounts so they aren't passive intakes for dust.

Some people, particularly gamers, might also put in a side panel fan to help cool the video card, especially if it has a weak fan that has to spin at high RPM by itself, and would wear faster as a result.

Depends on case design too. If talking bare minimums, the PSU fan and one more could get the job done, but then that 2nd fan would pull air past the CPU out the back, causing dust to come in every nook and cranny at a far faster rate, making every fan and heatsink less effective. Cleaning a filter panel is much better than cleaning out an entire PC.

I'm going to build this in 2 or 3 years time because my dad said that he would get me a gaming PC after my A/Ls. Depending on whether I have 3As of course. So there is a chance that I won't even get this thing. But because of his promise I've already started work even though schools have not yet started for A/Ls and I also have 2 1/2 years to go. So I'm pretty confident. I already checked out the parts I wanted because I needed to tell my dad the amount he roughly had to pay and I don't think I'm going to upgrade my choices when I do get to build the PC because despite the fact that this is a mid-range gaming PC, maybe even an entry level one, it still costs Rs. 240 000 in my country (including all the peripherals). Which is a lot. I'm glad to know that the fans will be enough cuz one customer had said that the RPM on the fans was a bit low but the description said it had 58 CFM. I'm getting four fans to keep stuff like my GPU real cool and also for aesthetic. Four RGB fans upfront and one exhaust one on the back. Thanks for your answer!

4 case fans. Mainly for aesthetic but also to support the cooling process of the GPU. I so will have a HDD installed. The case will have three fa s upfront and one exhaust one in the back. Is this setup bad? BTW thank you for your answer.

It's not bad at all. It's just overkill for your build (e.g. not needed).

That said, I have one exhaust and three intake fans on my computer (to run them at low RPMs to keep things quiet).

It will work but front and rear fans don't do as much for the GPU as a side panel fan, pointed right at it typically a couple inches away and blowing a little air over the back of the card helps too.

Acrylic side panels can be annoying to cut for a fan mount if cheap/thin/brittle but for metal, it's pretty simple to cut a hole. The worse situation is when they already put a fan mount in but in the wrong place and it overlaps where you want it!

In the past I've used cheap black plastic automotive door-edge trim to finish such cut holes. Inflation. This stuff was $2.50 last time I bought it. Maybe it still is in-store, online it has free shipping:


The type that has hot glue instead of a sticky tape liner, should be heated with a hair dryer and held in place until it cools. If you're using a filter panel instead, measure wisely and the panel itself may cover the cut edge of the hole.

I am going to have an acrylic side panel. Also the other side of the case (motherboard side) doesn't have any ventilation holes so I can't mount a fan sideways. But what my case does have is a ventilation hole directly under the GPU. So I'm gonna go for some more overkill and install a fifth fan directly facing the GPU. So I'm going to have 4 intake fans and one exhaust fan. Also the PSU won't have to compete with the other parts since it is a top mounted one and has its own ventilation fan directly sucking air from the environment. The personal GPU fan won't be suffocated since my case has legs. It is an Armageddon Kagami K5 ATX RGB Gaming Tower and it looks pretty good for the price.
