Need decent 500-600 watt PSU with 80mm fan

I currently have tried 2 different PSUs with 140mm fans and they all overheat because it is a top mounted case and it sucks the hot air into the PSU. So I figure a PSU with 80mm fan/fans would be a solution, and I need recommendations for a decent one in the 500-600 watt range.

I didn't think I'd find a 80mm-fan psu that I could in good conscience suggest to you, but I looked, and came across this one:

If the existing case is from a prebuilt computer, I still think you'd be better off changing that, since there are a number of good choices around the same price range. Here are a few examples:

There aren't any good quality ATX psus with 80mm fans. Nearly all good-quality psus use 120 to 140mm fans, and I think even psus with 80mm fans (which are generally poor quality and/or outdated) have those oriented as exhaust, so they'll still be pulling hot air from the case (though maybe not as quickly as 140mm fan models).

There are a few alternatives, though:
1. get a new case that mounts the psu at the bottom (with a filtered vent, so the psu gets air from below the case rather than from inside), which is a lot more common now.
2. get a high quality psu that can handle the hot air - there are some that can handle temperatures up to 50 C, and hopefully the air inside the case isn't quite getting that hot, otherwise you've got some airflow problems to deal with.
3. get a fanless psu, though the high quality ones might be very expensive.
 
If the air within the case is so hot that it's overheating the PSU, then you should investigate why that's happening. If a top-mounted PSU were to exhaust air into the case, it's just making the situation worse. A PSU needs to intake air to cool its internal components, hence why no exhaust-based PSU fans exist.

All in all, it'd be easier to buy a new case and use your existing bottom-mounted PSU.

It's a Pentium 4, that's why it gets so hot.
 
That's not very specific, but checking Wikipedia, the highest TDP I see for any Pentium 4 is 115W, which isn't as bad as some LGA2011v3 cpus which can get up to 150W even before overclocking, and others are able to deal with those without overheating their psus.

If the air in the case is overheating your psu, then either 1. the psus you're using have too low of a thermal rating (I think there are some that can only handle 25 C), or 2. your case has inadequate airflow (which you might be able to deal with by just adding a few fans, but if it doesn't have the fan mounts, you're better off getting a new case anyway)

I just want to replace the PSU that died in my fathers stock computer, with a stock case (obviously), which usually means terrible airflow. Anyway, the one that died was with 80mm fans, so it's probably better off using one with 80mm fans. It just needs to be "acceptable" quality.
