Cooling my Pentium D 915.
I've pretty much given up on the idea of keeping the temps on my CPU down, no matter how many times I apply thermal paste or change my bios settings.
But I can't take the noise of the stock fan. My question is, if I were to install something like a Scythe Katana II, would I still face the noise issue if it has to spin at 2000+ rpm to keep my CPU at 65 degrees?
I can live with the heat at this point but not with the noise.

Welcome to SPCR!
Another possibility is the Xigmatek HDT-S1283 (or it's KingWin twin). Here's the SPCR review:

Wow, thanks. The Xigmatek is available!
So I'll read the review too.
You think it'll make a difference because I'm seeing now that my RPMs are up in the 3500 neighborhood!
That's what I have to do to maintain temps in the 60s. This chip just runs too hot.
But if this fan helps I'm getting it today!!
Thanks again.

Basically the bigger the fan (all things being equal) the less rpm it has to do to shift the same amount of air (measured in CFM). Lower rpm is the simplist way of reducing noise.Nocontact wrote:Admittedly new to quiet cooling, does a 120mm fan make a difference in terms of noise?
And 120mm fans have established themselves as the default for high performance, and all the developments in reducing noise tend to go into 120mm fans. There are some 140mm fans, but because they are pretty rare still its often the case that a good 120mm will be better. Anything much bigger becomes unwieldy inside a case.
Check out the Recommended list on the SPCR homepage for the best fans, although personally i recommend Scythe's Slip Stream series. Can get 5 different speeds ranging from very high to very low, and they are cheaper than alot of their rivals.

Well, there really is not Heatsink fans and Case fans really. Scythe delivers Slipstreams in their newer revisions of Ninja and Andy Samurai was it? So no, they're same thing. You easily can use Slipstream in there. I intend to favour S-flex on Heatsink due it has higher impedance than slipstream, albeit slightly more noisier and tonal. But I use SI-128 SE on my game rig, which has very narrow finspace. I believe Xigmatec would work well on slipstream.

The TDP on your 915 is 95w. My P4 Prescott 530 is 84w, so I do understand your situation.
These high TDP processors draw high power from somewhere, and that somewhere is the VRM. My Prescott runs the VRM temps way up due to power draw. You MUST consider VRM cooling when choosing a cooler.
The tower super coolers will keep a hot processor cool, but they offer almost nothing for VRM cooling. IMO, you should consider a top-down cooler rather than a tower for this reason.
In lowest cooling order:
Scythe Andy Samurai
Thermalright SI-128SE
Scythe Zipang
The first two use a 120mm fan standard. This offers a wide variety of fans speeds for your choice. The Zipang uses a 140mm standard fan, and can accept a 120mm if you want to Mickey Mouse how it is mounted. 140mm fans are much more limited, with the Yate Loon being the fastest of the bunch. I use 140mm Red Scorpion fans on my Zipangs.
I put a 120mm Panaflo 12H on the Zipang, and it cooled my hot VRM down to ambient. It is noisy, but can be undervolted. See my other thread about Zipang in this section.

The case is `190mm wide so if you include the mobo and the cpu that doesn't give me much room to play with if any at all.

I'd probably go for the Ninja either way. more heatpipes, wider fin spacing...you fan doesn't have to be blowing hard to have a large margin of a difference in cooling.
either cooler though, get the Thermalright LGA775 bolt-thru kit. it is compatible with both the S1283 and the Scythe Ninja. The pushpins on the Xigmatech seem to be loose or crappy on a lot of them, so i wouldn't trust them with anything.

i dunno what you're reading, but only the Ninja Mini has a 90mm fan. the full sized Ninja (which is what you'd want) only uses a 120mm fan.the ninja has a 90mm fan as opposed to the 120mm fan.
you could also improvise a bolt-thru method, as a few people here have done...they have more even pressure, and are better than pushpins by leaps and bounds.
