P4 2.26Ghz with heatsink and no fan?

[BenW]

Right, looking at getting a new case/motherboard/heatsink to finaly get rid of the dell proprietory parts.

I have a P4 2.26Ghz 533FSB northwood.

I'm probably getting the Thermalright XP-120 if i get a heatsink but with a tightish budget i want to save buying a fan for a little while.

Will it be alright to run all this with just the heatsink, a 120mm case fan and 80mm one in a silentx PSU(Normal ATX/ no shuttle)?

Thanks
Ben

try undervolting the cpu a bit and then see what the temps, i think the xp-120 needs a bit of air, but you maybe ok, i would be inclinded to have at least a fans pushing off 7v and then it would be silent.

[BenW]

The case comes with a 120mm fan so i could put my current 92mm on the case (Has mounts for both) and then put the 120mm on the cpu

It's a possibility but i was thinking about just having the XP-120 on its own

At the moment its just got a heatsink on it but it has a shroud/duct on it going to the only rear case fan.

I think it will be fine but just want to make sure, the XP-120 is a massive heatsink

Northwoods get hot, you'd be pushing it if you could.
Get a XP-120 and a SilenX fan (get the 14db one, you wont be able to tell).

Northwoods? I thought northwoods were quite cool and prescots are hot?

[Timmy!!!]

Yep Northwoods are cool, you will probably be able to do this. Just remember to keep an eye on your temperatures just in case. Prescotts are the hot beasts.

Not a good idea unless you monitor the temps of the cpu under load and see if it's within resonable limits ~60C?

[BenW]

So how do i do that? I don't think the motherboard i'm looking at getting has a CPU thermometer, i'm looking at the Gigabyte GA-8IPE1000 Pro-G

[HKPolice]

The thermal probe is built into the CPU, all P4 boards support it. Motherboard monitor is the most popular prog: http://mbm.livewiredev.com/

Gigabyte has their own hardware monitor prog too.

Northwoods are only cool compared to the Prescott, compared to everything else they're still plenty hot. You could try undervolting it though ben-wade, that does help to cut heat by a lot. You could also run it at 100FSB if you don't need a lot of CPU power.

[BenW]

Wasn't aware that the temp probe was in the P4. My board in the dell doesn't support reading from it (Intel board i think)

If the motherboard supports under volting then i will be doing so, would rather under volt than overclock to be honest, don't want to run it a 100FSB as i play a lot of farcry etc and i like the high setting!

[Timmy!!!]

Yea all modern processors have temperature probes in them so they have some sort of temperature alarm system. For example P4s slow down if they get too hot (70 degrees ish) to stop them from burning out.

I'm sure your motherboard does support temperature readings. Download speedfan (google it) and see which temperatures you can see. The temperature that fluctuates the most is usually the cpu.

[BenW]

I have speedfan and its hard drive temp only
