Looking for a new heatsink

[AL BE]

My stock heat sink isnt preforming very good. I have a p4 2.8 478 it run at 34 idle and 59 full load. I aslo am looking to do some light overclocking. I am looking for one that is under $50. any suggestions

I've had good results with a Zalman 7700Cu.

Light OC of a 2.8 478,mmmmm.

<$50...XP-90 from Jab-Tech.com @ $28 + at least a 50cfm 92mm fan of your choice.

Bar none, the low speed 92x38 Delta Triple Blade fan is one of the best out there but Jab-Tech doesn't offer it yet.

Go to epowerhousepc.com. You can have the XP-90 + the 92x38 Delta Triple rated at 57cfm
at your door for under $50. If you get this set-up you will thank me later.

Nothing wrong with the Zalman 7700 but the XP-90 is better for OCing a toaster CPU. I have two P4 chips

Yeah -- 34C to 59C is a bit of a stretch. Galvanized has good advice.

The ThermalRight SI-120 is about $45. I've had marvelous luck with it on an over-clocked Prescott with mobo ducting.

I swear by heatpipe coolers, if you're not planning on a water-cooled or phase-change solution -- and I dare say -- you're not.

A socket 478 2.8Ghz (is it the Northwood or the Prescott-retro?) -- should not be running that hot. It won't hurt it because you're within the thermal limit, but if I can keep a Prescott 3.2E @ 3.5Ghz below 39C running S&M (100%) or Prime95 (Large FFT test) at room temperature of 70F, you can certainly do better than you are.

Scythe Ninja. Easy.

Well, ShadowK, I won't get into a p*****g contest.

We were able to show a couple months ago with the appropriate review results that the Scythe slightly (ever so) outperformed the SI-120 at high fan rpms (~2,900), but the SI-120 slightly outperformed the Ninja at low (950) rpms. It's a wash on cooling.

It's not quite a wash on weight, but the Ninja is still light enough that it wouldn't make too much of a difference. And the fan deployment doesn't need to hang the fan on the Ninja if the "case is right."

That leaves case design, fan deployment, and aesthetics. I can see where the Ninja might be the better choice in a mid-tower case where it fits close to a 120mm exhaust fan and a PSU (120mm) fan perpendicular to the case exhaust would be an ideal fit for a Ninja. In that arrangement, you don't need mobo ducting to get at least the same performance out of the Ninja that you'd get with the ThermalRight cooler supplemented with the ducting.

And . . . actually . . . I was too kind in deferring to the Scythe Ninja's performance.

Look at these test result comparisons:

Hi-Techreviews- - SI-120 to Scythe-Ninja comparison test results

Now here, they've picked one of those low rpm fans running at about 950 rpm. I was a bit surprised to see that the temperature spread in the SI-120 test is only about 2C wider than my own SI-120 with the fan at 1,800 rpm.

Unfortunately, the review doesn't use a higher-rpm, higher-CFM fan for additional comparison, because it would probably support my point in the earlier post. Or at least, we can give it the benefit of the doubt . . . .

Remember, the OP said he wanted to do a"light" OC and keep the HSF under $50.

I really do think the XP-90 w/Delta @ 57cfm to his door would be the way to go.

You have to try one of these fans BonziDuck. Sweeet, undervolt to 4V EZ. Starts and runs at 4V in complete silence. At full song the sound is deep and not irritating at all. The Panaflos i bench tested against the Delta Triples didn't stand a chance. Wanna buy some 92mm Pans?

AL BE, it would be useful to know which P4 you have. The 2.8GHz was made in five different models for socket 478 (2.8, 2.8A, 2.8B, 2.8C, 2.8E).

For a budget recommendation, the Thermalright XP90 can be had with an included fan for about $35.

 

[AL BE]

I Know its a northwood core and i think its a 2.8c

 

[Zap]

Unless you're overclocking to 3.5GHz (and yes, some of the 2.8C chips can do that) almost anything decent will do. What is your budget? How do you feel about fan noise?

The one I mentioned, Thermalright XP90 with fan for $32 (currently OOS) is a nice one for being mid-high priced. If you want closer to your spending limit, consider Zalman CNPS-7700 series. Amazon currently has the all copper version for $39.XX with free shipping.

Well, actually you kind of did there... My recommendation is based on decent cooling, with the option of running it passively to decrease the noise floor (potentially) in his system. The end. Whether it's the absolute best cooler or not is irrelevant to my recommendation.

This shows the Ninja doing better than the Si-120 with a slower fan. There's no comparison on really slow fans, though. http://www.overclockers.com/articles373/p4sum.asp

To reiterate, my recommendation is based slowly on lower noise levels (running passively). I don't care about if anythings better if it requires a fan to woek well. My Ninja worked perfectly well at cooling in a 3700AMB with a Nexus at 650rpm, next to a passive PSU, so you don't need a PSU fan to cool it off in addition to the case fan.

I like the thermalright xp90 with the fan for $32 do you have any idea when that will be available. I was also looking at the Zalman CNPS-7700 but i think i will have clearence issues.

 

[GalvanizedYankee]

Jab-Tech.com has the XP-90 in stock as OEM and retail. The retail is $31.95 w/fan.

The OEM is $27.95 w/o fan. They charge no tax, ship quickly and don't pad the shipping cost.

They are very responsive via Email. You will have a tracking number quickly. I have an order due from them tomorrow. Good folk to do business with.
