533 MHz FSB Pentium 4 Processor for a Dell Optiplex GX280 machine
I have a list of possible cpu upgrades for a Dell Optiplex GX280 computer (mini-tower), and all of them are working at a 800 FSB freq even though the motherboard supposedly welcomes 533 FSB freqs as well, at least for the RAM memory part.
My question is whether I can use a CPU like the one showed in the following link from official Intel website for a Dell Optiplex GX280 machine:
And if the answer is a YES, will it be a good idea as far as cpu temperature goes, I mean if I use a 533 FSB CPU and also 533mhz RAM memory?

From the Spec I would say it should be fine. Bios should be updated to latest version BEFORE changing CPU.

2 Heatpipes sounds like DESKTOP not Tower.
W4254 Dell Performance Heatsink is on the tower.
Non Towers will HALT UNSUPPORTED CPUdue to power supply size for processors over 2.8Ghz. 280's come in 2 Tower Flavors The MR Smith Tower and the Skydive Tower.
Regulatory Model (Mini-Tower): DCSM or DCSM1F
Regulatory Model (Desktop): DCNE or DCNE1F
Regulatory Model (Small Form Factor): DCCY or DCCY1F
Regulatory Model (Ultra Small Form Factor): DCTR or DCTR1F

The higher freq processors require the performance copper heatsink
I doubt that the GX280 supports the HT technology.
Performance Heatsink Assembly, MiniTower, Dimension, W4254 and faster Ram. My question would be why are you trying to upgrade such an old unit. Mhz doesn't = performance. This is why Netburst was abandoned in favor of Core 2 Duo. 1.86Ghz core2 duo is faster than 3ghz Netburst processor.

A GX620 or better Precision 380 would be a better choice.

I do have a copper heatsink (i doubt it is the performance model, it only has 2 copper spires), and I currently use a Prescott, 520, 2.8G, 1M, 800FSB which consumes a lot of power and has built-in HTT technology (i'am using it right now, it is enabled in bios settings together with DEP/NX feature). Unfortunately this cpu model does not support intel64 feature, and I was trying to use a similar alternative, same power draw, litography etc, but working on a different FSB, hoping to get intel64 feature too, and also keep the cpu cooler.
Intel Pentium 4 524 CPU model looked like a nice alternative but it runs at 533 FSB, and I have no idea whether my PC, Optiplex GX280 can handle 533mhz FSB or I get stuck to 800mhz FSB models only.

First of all, thank you for the accurate description above, it is more than useful, and the images speak for themselves.
My computer is the big guy up there (12kilos+) you posted right under the performance heatsink picture, it is the mini-tower model for Optiplex GX280. I recently learnt about the performance heatsink, and I did try to buy one from the same store that sold me this computer (it is a SH machine) but they told me they have nothing available.
I needed that performance heatsink because I managed to get a processor listed on the official upgrade list for GX280 CPUs, namely Pentium 4 Processor 541 which runs at 3.2Ghz and 800 FSB. With the current heatsink with only 2 heatpipes that particular processor run kind of hot, and I decided in the end to go back to my default Pentium 4 520J (2.8Ghz, 800FSB).
I think you provided me with the right answer, so in the end I could use a processor which runs at 533Mhz FSB but I guess it will have to be one with this feature - Lithography 90 nm - instead of one built with this feature - Lithography 65 nm - or something like that. As long as it stays cool and it is stable, I am ok with something slower than 2,8Ghz, maybe 2,6 or even 2,4, I don't mind that especially if I can run WinXP x64.
