advice on heatsinks

Re: advice on heatsinks

Yer that is one nice looking heatsink too! Rated for Athlon XP's upto 3000+. I think that will be ample for a 800Mhz P3.

Re: advice on heatsinks

What the...

I have those masscool's also, don't get them, they are major junk. The bottoms are poorly machined (they will slice up your die, HUGE think endmill marks) and have a super tight clip. (CRUSH)

Those are the coolers I bought before I bought the rosewill/thermaltake's. I bought two, and RMA'd them to newegg and they just refunded me and told me not to send them back. At least I got two fans out of the deal.

Re: advice on heatsinks

i found a good one at my local electronis shop. i didnt buy them now, 20 bucks a pop. they are these:





http://www.speeze.com/main/fcc_v2.asp?ProdID=245

they are speeze LightOwl II "™ EEA86B4 fans. no leds in fan on theirs.

found them when buying a new solder sucker : all aluminum spring powered compact solder sucker. i had to sand a few sharp edges and wd40 the seal, but as long as you regularly clean out the tip after a sucking a large blob, it works like a million bucks.

i bought mine a few years back. no problems. no marks on bottom other than from getting thrown into a spare bin. the marks were nowhere close to my core. so forget the all coper thin fan is masscool is bad.

Re: advice on heatsinks

Speeze is masscool. Check the bottom if you can, it should be smooth. My masscool's I got (same as both the previous you have posted) had very poorly machined bottoms, with deep endmill marks. Not only was this poor for surface area, but it would put big lines and gashes in your die of the cpu.

Re: advice on heatsinks

they had smooth, mirror bottoms

Re: advice on heatsinks

Thats what it looked like in the picture, I think the ones newegg got were a bad or early batch or something.

Re: advice on heatsinks

i do have a speeze s478 with deep cuts. but these seemed better. i don't have the money for that this week (my mom likes to limit how much i spend at the electronics shop)

is it a good or bad buy for $20?

Re: advice on heatsinks

I don't like pressed in copper slug like I explained before with this type of heatsink. The heat conduction is limited to 2/8" thick edge around the plug and goes long way around the aluminum heatsink and up the fins.

The retail intel heatsink slug is most of the height of the heatsink and radiates to the fins evenly.

Other heatsink I like is forged heatsink with large area copper on base with fins aluminum on top.

I need to get picture up later.

BTW, don't pay 20 bucks for those typical heatsinks, invest around 40-50. This gets you good fan and quality heatsink.

Best thing is save up your allowances.

Re: advice on heatsinks

Dropping 40-50 on a p3 heatsink seams like a waste, if you are going to go that route just save up your money and get a nice p4 or A64 board for cheap and a 3ghz p4 or 3200+ or so are pretty cheap, also.

Re: advice on heatsinks

they had an all copper one for 32 bucks. but it was a microfin.

[ratdude747]

Re: advice on heatsinks

is there a way to mount an am2 hs on a 370 socket. they looked similar.

[ratdude747]

Re: advice on heatsinks

so, wizard, i wasted my money by buying a replacement p3 board. i should have saved up for 5 years so i can get an appropriately sized one , the size ofman engine block.

really, i dont get an allowance exactly. i get things here and there. right now i dont get too much. i dont know how all of you afford fancy water cooled 2000 dollar sytems in this economy, but i certainly cant. i cant get a job because there are no openings. i know i could be a petter repair tech than some of the current ones, but i am still in high school so no dice.

take that in consideration with the advice please.

Re: advice on heatsinks

No one is saying you wasted your money on your p3. They are stable, still pretty fast, cheap, and don't use up nearly as much power.

I was just saying if you are going to drop 40-50 on a heatsink just for a p3 (btw i have never seen a $50 p3 heatsink,) they you might as well start saving up for a p4 era computer, you can always get a decent one for about 100-150 dollars.

Re: advice on heatsinks

I agree but for now try to find these on ebay.

Left to right:

Intel retail P3 heatsink, middle is forged heatsink with copper compressed in there (cold weld), right is IBM Netvista PC (this one have nickel-plated copper thick plate glued to the heatsink).

Alpha heatsinks do turn up from time to time on ebay and it was only option back then when people needed a GOOD one when K6 and faster socket P3 started to come out, and during athlon era due to rising watts and fans were so bad, heatsinks even worse. Even the thermaltake was no better than Intel's with dual ball bearing fans are not bad and thermaltake only serves to empty your pockets, fan on these were poor.

Delta produced good fans as well, NMB, Nidec and few others. Look for these.

This forged heatsink I have is what other competitor made that Alpha made for heatsinks.

Here's photo of 3 heatsinks:

This will get yoiu started for search for good heatsinks, there are other makers of good heatsinks out there.

Re: advice on heatsinks

i already have an emachines with a p4. presscot. replaced the power supply because it had a burned up bestec 250w. charred wires and such. replaced with a modded delta 350. 1.5gb ram. 250gb sata hd

i upgraded the cpu in it from a 3.0ghz 533fsb no ht to a 2.8ghz 800fsb with ht. the heatsink is a massive with thickish fins with plenty of space for between. pwm fan with a duct attached to feed a side case vent. i took the ductoff and flipped the fan. it is all aluminum cooler master.

i like the p3 because it has a video expansion slot (above did not, onboard only), takes ram i already had, and runs ubuntu decently. i dont have 100 bucks for a new computer. there is a reason why i only use crt monitors at my house. there is a reason why the computer above is the fastest thing in the house. also second newest, my eee pc is #1.

so the question is will those speeze fans work or not. im not asking how much to spend or whether i need a new system.

Re: advice on heatsinks

and the first one doe not match my retai heatsink:



thats my retail one., but mine has the 3rd wire

Re: advice on heatsinks

This black retail heatsink one is very old retail heatsink (had one and not sufficient for PIII 700 and up) and it was used with socket celeron 333-400-500 fsb 66, socket PIII 450-600 or so fsb 100. The later ones is much larger and bare aluminum color.

Re: advice on heatsinks

but will the speeze work or not? for 20 bucks is it a good deal?

Re: advice on heatsinks

People always get confused with forged heatsinks.

No heatsinks are forged, forging is the process of heating up a piece of steel and essentially banging into the shape desired. No way a machine can forge in the fins, the metal on the bottom in between the fins would be incredibly dense. They are extruded, where they take aluminum stock and force it through a heatsinks shaped die to make a long string of heatsink that are then cut into the appropriate length.

http://en.wikipedia.org/wiki/Extrusion

"Aluminum is the most commonly extruded material. Aluminum can be hot or cold extruded. If it is hot extruded it is heated to 575 to 1100 °F (300 to 600 °C). Examples of products include profiles for tracks, frames, rails, mullions, and heat sinks."

That masscool may be ok,

That looks promising
