I'm looking to upgrade my CPU from a Intel P4 2.00 GHz 400 FSB to a Intel P4 2.8 GHz 400 FSB. I've seen some chips on ebay without a stock fan. I have a fan from the chip I have now. I've was planning on overclocking this chip. Can I use the stock fan I already have or should I get an after market fan?

The fan you already have should be enough for standard speeds. But an aftermarket would be a better (but more expensive) option.

Look at the "ThermalRight XP-90" and "Zalman CNPS9500", and if you can fork-out for them. They might be worth getting, especially if you're planning to overclock a pentium (which are usually pretty hot at stock speeds).

I would also check out eWiz.com. They have the OEM Pentium 4 2.8E 1MB cache 800mhz FSB for only $105.06. I'm finding this website to be a little gem:

The HSF's recommended by RoD are very nice. Also, check out the Scythe Ninja. However, all of these are very large heatsinks, so make sure you have the clearance on your mobo and room in your case. If the price is a little steep for you on those, then Howard's recommendation is a very nice one, especially at that price point. One thing, though, are you going for the Socket 478 2.8E or the Socket 775 520 or 521?

socket 478...I dont think a p4 2.8 GHz is recommended for my board (GA-8IR533). I believe the highest PCU is a p4 2.6 GHz 400 FSB

A very cheap but very good alternative to the expensive Zalman and Co., could be a fan from Arctic Cooling
I've just installed one Super Silent 4 Ultra TC L from Arctic Cooling, and the easy installation without screws is extraordinary good. Good is also the cooling performance and the super silent fan.
Another cheap alternative with good performance at very low noise are the Spire Cooling Solutions

But if you're going for overclock, I would recommend you a lot more than just a better CPU fan.

When you have replaced the 2,4GHz with your new 2,8GHz, you will feel the gained speed so that an overclocking isn'r really necessary for beginning. You should test your new CPU with its common values in daily work. Then when you will become an eye for its performance, you could think about testing its maximum, for what reason ever.

I went the same way once, starting with the 1,7GHz Willamette FSB400, then upgrading to 2,4GHz Northwood. But I wasn't really convinced about the achievement. In accordance to my mobo, D1325 from Fujitsu-Siemens, the 2,4GHz (GS stepping) was the fastest CPU that fits. But of course I didn't believe it and I've placed an 2,8GHz Northwood FSB400 on it. The BIOS didn't recognize the CPU, not after the latest BIOS update and also not after the Micro Code Update. But I was booting with F1 (Resume) and the Windows recognized the CPU as a P4 with 2,8GHz.
The difference between the 2,4 and the 2,8GHz is so immense, especially for the complex routines, that you won't think for overclocking at first. Configure the entire system properly instead of this. When all components are set in balance to each other and when your OS is properly set up; that is much more worth than an overclocked CPU which is running in wrong mode.

Cheers!;)

If I read you post right Perfectibilists, your saying that I can put a 2.8 400 FSB into my mobo (GA-8IR533)? I must tell you i dont have alot of experience with building PCs and I've only been reading things on this board for about a week. I currently have a p4 2.0 and wanted to upgrade so some of the higher end games I have are not so choppy. As I said before the specs only rate a 2.6 GHz CPU for this mobo...so...what do you recommend I do?

As said above, with the higher cpu speed & overclocking a new fan with more airflow cfm rating is your best option.
Besides, you do not know how much life is left in your old fan.

Ola Sr. Paco:)

I'm not an expert on all mommas but I would say (corrections welcome) as long as it is a FSB400 CPU, you could put anyone (Northwood) on it. When it says that your mobo supports only up to 2,6GHz then you would probably get the same error message as I had when booting with 2,8GHz. (Unknown CPU Type... bla bla...)

Usually one says that it is not wise to chose the latest/fastest CPU of a serie, especially for overclocking purposes. The 2,8GHz is the latest CPU with FSB400, so perhaps your supported 2,6GHz wouldn't be a bad choice to try.
I had the problem that my mobo was locked and so I couldn't upgrade through software but had to change the entire hardware, therefore the 2,8GHz made sense just in my special case.
Actually the core is the same, and your 2,6GHz (Multiplier 26x) wouldn't be nothing else than an overclocked 2,8GHz (Multiplier 28x).
If you want to OC, buy online a cheap, used 2,6GHz FSB400 and when you feel that the time has come for more, 'clock it (through BIOS or comfortably through Software like SoftFSB or CPU Cool etc.) to 3,4GHz (with CPU cooling, GPU / VGA RAM cooling, DDRAM cooling, Mobo chipset cooling and multiple Case cooling), so you won't miss the 2,8GHz.:D

Hasta la vista!

Sorry but I have to quote myself:

I was meaning of course the 2,8GHz is an overclocked 2,6GHz:roll:
