Pentium D Overclocked - XP90 or XP120?

rx2 · Post by **rx2** » Fri Dec 16, 2005 2:11 pm

Hi,

I am trying to choose a cpu for my Pentium D 2.8 that I overclock upto 4Ghz. At the moment it's getting way to hot so I am looking at either the XP90 or XP120 (I had originally looked at the SI-120 but it's just to tall for my case).

I am not to concerned about noise difference between the two heatsinks.I
was planning on using the recommended panaflo fans with the heatsinks.

But is the XP-120 drastically better than the XP-90 in cooling efficiency for the Pentium D overclocked processor?

Any opinions on this?

Cheers

Robert

I don't see any reason for getting an xp90 as you will be limited to 92mm fan choices. You will need a medium speed 120mm fan with an xp-120. - FG

I've seen comparisons that rated the XP-90C above the XP-120 in cooling performance - Only the C version though.

Do you have a link for the comparison?

The reason why I am thinking that the XP-90 might be better is because it isn't as tall and bulky as the XP-120. The XP-120 will partially cover up my rear exhaust fan, whereas the XP-90 will sit just below it. The XP-120 will take quite a bit volume/space inside the case restricting airflow whereas the XP-90 wouldn't be.

Like you Frank my initial idea was to go straight for the XP-120 but I was concerned about the airflow within the case with it consuming so much space. If the XP-90 is very close in comparison with the XP-120 in terms of cooling then I would prefer to get something smaller like the XP-90 and have better internal case airflow?? Opinions?

Btw I have an Antec SLK3000B case.

I have the same case, had an xp-90, and the xp-120 with the same amount of fan noise will be better. The 120mm fan extends over the edges of the xp-120 and blows air on the mb. A medium speed panaflo is rated at 48cfm@2450rpm. The aluminum everflow 120 is rated at 80cfm@2000rpm. Plus the xp-90c weighs a lot more. - FG

Well it seems to be a bit of a toss up between the XP-90C and XP-120. I have read a couple of reviews and like ceejay says, the XP-90C comes out on top by a small margin.

I take your point Frank about the weight and getting more performance out of the XP-120 at the same amount of fan noise.

What I need to do in order to help reach the decision is find out whether the XP-120 will fit the Asus P5LD2 Deluxe motherboard? Does anyone know?

Here is a picture of the m/b :

This review lists the p5ld2 used as a testbed with the ninja and xp-120. Maybe you should get a ninja? Only drawback would be less air flow directed to mb. - FG

OK... I have decided going to give the Ninja a whirl and see how that goes.

One thing that crossed my mind - I have a side port on Antec SLK3000B case that is positioned over the CPU. With the Ninja having the fan attached to the side of the heatsink, this side port becomes redundant in effect with that cooler? Obviously if I went for the XP-120 it could take advantage of the side port as the fan is mounted on top of the heatsink.

So, I presume I will now have to ensure that there is more than adequate airflow entering from the front of the case? At the moment I don't have a front fan, but I think with the Ninja it's going to be a must. My theories correct?

Not necessarily. I wouldn't put a fan up front for intake because, in my experience, it's warmed things up more than it cooled them down. By having more exhaust fans than intake's you create negative pressure - air will automatically be forced to be drawn from the front. With an intake fan you're going to lose some of that negative pressure, and possibly reach equilibrium or create positive pressure. In some instances this works out well, but, again, my case it didn't.

The SI-120 works very well in the SLK3000B; you just need to trim the CAG if you want to use it. I've noted better temperature results all around in my SLK with the TAC duct removed due to improved airflow. Also, keep in mind that the chipset radiators require some airflow, the SI/XP-120 blow cool air down onto the radiators, the SCNJ-1000 does not.
