Switch Pentium 4 630 for a Celeron D 356

[joaoparaiso]

Hi.

My brother's PC has a P4 630 (3.0 GHz) Prescott with 2 mb L2 cache. Since he complains a lot about the high temperatures, I thought it could be a good idea to switch it for a Celeron D 356 (3.33 GHz).

First of all, the Celeron is made on 65nm technology whereas the P4 is made in 90nm, so it should run a lot cooler. I can sell the P4 for 65$ and get the Celery for a mere 40$, so my brother will earn a few dollars if he does the exchange.

But I'm a bit concerned performance-wise. Although the Celeron has a 333 Mhz clock speed advantage, it also has only 512 Kb of L2 cache vs. the 2 Mb of the P4. Do you think they will run neck-to-neck, the Celeron will have an upper hand or the P4 will crush the Celeron? And how much cooler will it be (now it runs 46ºC idle and 67ºC full load, with stock HSF)? In summary, is it a good idea to switch the P4 for the newer Celeron? (please stick to this comparison, I know a Core 2 Duo E4300 would be the ideal solution, but my little brother just hasn't the budget for it). Thanks in advance.

Yep, lower performace.

Best to just buy a good heatsink, put soem case fans in, and clean the dust out.
I have this cooling my Overclocked P-D 805 to 3.4Ghz

You could get a 65nm P4 and be content with that. Maybe even a dual core 65nm 900 series. Last i checked they didnt cost too much more than normal P4's and some 900series actually cost less.

Go to a Pentium D 925 if your brother has a 945/955 based solution. If you want lower temps you can go for a Pentium 4 631 which is the same processor but on the 65nm node. it's only 59 USD for the OEM version on eWiz. If you can get a D0 Stepping they are 65W TDP processors. I had a Celeron D 347 D0 Stepping and it ran quite cool 37 idle 42 load.

If you have a motherboard with Core 2 Support then their is an alternative.
If your brother doesn't have the budget for the E4300 maybe this processor the Pentium E2140 would be to your liking only 91USD. It's a bit slower then the E4300, 1/2 the cache and 200MHZ lower.

Yeah; Core 2 would be ideal if your board would support it; any C2D chip would be a good deal faster. Second choice would be a Pentium D, third choice would be a Cedar Mill based P4. If you go Pentium D, try to get a 9 series as they are 2 Cedar Mills, but the 8 series is 2 Prescotts. You should be able to find any of those chips, except maybe a Core 2, for really cheap in the FS/FT forum, or just check at some etailers.

Installed one of these for a customer with a P-D 945 (HOT!), keeps it in the 40s. Should do wonders for your bro.

The celeron will be slower, 67c is an acceptable temp for those CPU's, sure it's hot, but it's well below the throttling point. 65nm CPU's will deffinatly run cooler, but only if the motherboard actualy supports them. Just because they are LGA775 doesn't mean they will work. Does his case have good ventilation, did he make sure the heatsink isn't clogged with dust? Tried replacing the thermal grease with some artic silver 5?

His motherboard is the popular Asrock 775Dual-VSTA. Given the budget, perhaps I should buy him a 65nm Cedar Mill, because he really doesn't want to spend more than 60$ on the CPU.

Lol, so he has the same motherboard as I, well like I said the 65nm Pentium 4 631 or if your willing to stretch the budget a tiny bit more then Pentium E 2140.

if you can, you should definitely do that. if your brother is satisfied with the performance of the pentium 4 though and only wants lower heat, the 631 would be fine, but if you just get a good heatsink for your current chip (i'm assuming he's using stock cooling?), you'll have lower temps anyway plus you can use the new cooler on a c2d if you upgrade later. plus it's probably cheaper than a processor upgrade (unless you find a deal or someone selling a cedar mill).

just glancing at the egg, those are all pretty cheap and look pretty good, i know Arkaign recommended the 4th one already, if it keeps a pentium d 945 in the 40's, itll do wonders for your prescott, and if you upgrade to C2D later it'll still be an awesome cooler; both of those chips are much cooler than a pentium d 9 series.

EDIT: oh, i dunno how well the wires in the case are routed, and i know this is pretty basic, but you should route those out of the way to increase airflow if they're not already. also, again i know basic here, make sure there's at least an intake (bottom front) and exhaust fan (top back under psu) and that they aren't being obstructed (basic, i know, but idk anything about your brothers computer except his processor is really hot).
