5 out of 5 eggsVery nice.

Pros: I've found no need to overclock this, but tried it anyways I overclocked it to 3.84 running super cool with a Zalman Reservoir, cpu water cooler never goes higher than 60-63 C.

Cons: None with a 3 year waranty through Intel there should be none untill I decide to buy a new pc and burn this baby.

Other Thoughts: Deffinitely get rid of the fan that came with this because it runs 60-65 C with it and thats what you can get with a 20% overclock with a water cooler.

5 out of 5 eggs

Pros: Very Fast and I love the dual core. I'm using the stock heatsink and it idles around 55 but under load is only gets up around 60-65 which is kind of hot, but Pentium D's do tend to run a little on the hotter side.

Cons: None

5 out of 5 eggsThis thing is a beast

Pros: FAST FAST FAST>>>>.... No problems with this CPU.. Benchmarks high. I overclocked it up to 3.9GHZ. Running stable. For the price how can you go wrong

Cons: Not a one...

Other Thoughts: Dual core is great. Very handy I install games and play a different one at the same time. Can't go wrong there

5 out of 5 eggsRepost

Pros: Very fast and stable during overclocking. With the Ga-8n SLI Royal motherboard and paired with 4x512Mb Corsair XMS2 DDR2533 with 3-3-3-8 timings. I was able to overclocked it from 3.2Ghz to 3.840Ghz that is 20% overclocked. The ram is now at 400 with 3-3-3-5 timings. It is on air cooling with Thermaltake Big Typhoon and runs at 45c idle and 55 full load at normal room temperature.

Cons: Was expensive back last November when I first bought it. Now the 940 is better with lower price.

Other Thoughts: Hot running cpu, so with artic silver 5 and Thermaltake Big Typhoon got the temps to a reasonable levels.

4 out of 5 eggsRepost - It is so dang hot!

Pros: As I said before in so many words, it is a true workhorse. I haven't tried a single core for this application, but I use the computer as a Media hub. The Xbox360 pulls video over GB ethernet, while I can watch another video or play a game with no adverse effects. The dual core, I believe, is very good at mutlitasking.

Cons: Very, very hot. Too hot. I just swapped out the Zalman CNPS9500 and VF700-CU (CPU and GPU) for a Reserator I Plus. Idle is in the 40s (same as air cool). Load is high 60s, about 8-10 degrees lower than air cool. Yes, of course, I used Arctic Silver 5 and I am getting pretty darn good at spreading it evenly.

Other Thoughts: This may just be that the Reserator and its water blocks are only average in exchanging heat. I put a 20" house fan on high blowing right on the Reserator. It only dropped the temp about 5 more degrees. I am dreaming up some mods for the reserator. CPU load was accomplished by running two versions of CPU Burn-in v1.01. Unlike any other normal behavior where loads are fairly evenly distributed, one session of CPU Burn-in only pegs one CPU. Cool, huh?

Anyway, this beast keeps the room about 5 degrees hotter than any other room in the house.

It is likely the Pressler core with the 65nm architecture runs cooler.

5 out of 5 eggsMine's not a space heater

Pros: Runs as it should. I don't see the high temps others are reporting. Ran 2 instances of WinRAR compressing 1GB folders simultaneously. Task manager showed 50% CPU usage for first iteration, then jumped to 100% once I started the 2nd compression, so both cores were getting a workout. After 3 min, max temp (monitored thru Aida the whole time) was 47C. Idle is 32-33C.

Cons: Pricey. Not a huge noticeable performance gain over the 3.0 Prescott it replaced - until you start multiple CPU-intensive apps.

Other Thoughts: I'm using a TT Jungle 512 heatsink w/ it's stock thermal grease - nothing fancy. In a full tower (huge) case w/ 4 8cm fans. There are also 2 optical drives, 3 hard drives, X850XT video card, USB add-on card, & IDE PCI controller card. Very meager air-cooled system, but this CPU doesn't overheat.

5 out of 5 eggsIntel Pentium D 830

Pros: My PC is running on a Intel Pentium D 830 processor with liquid cooling system which chills the CPU to the bone. I also upgrated to 3GB of ram, PC4200 DDR2 at 553Mhz, 160 GB HDD raptor at 10,000rpm with controller, ATI-Radeon X1900XT 512 MB video card. i run multiple apps simultaneously, it never gets hot of clumsy.

Cons: i think all components within PC are not less greatly essential to correspond to the performance of the CPU.

Other Thoughts: I'am extremely satisfied with the performance of Pentium D Processor. i also installed 2nd O/S XP 64 bit edition on the same HDD using the system commander. it works supersonic fast.

4 out of 5 eggsSupercomputer & Heater all in one

Pros: It hasn't stuttered yet, it keeps my legs warm.

Cons: Very Hot (like high 70s at idle). The standard heat sink is not sufficient.

Other Thoughts: I have a Media Extender (xbox360) that pulls video from it while I play games at 1600x1200. I have about 80 processes running on it and have never seen either CPU at over 60% or seen any CPU-like patterns for overload behavior.
I replaced the heat sink with the ZALMAN CNPS9500 and it blows right at two 120mm fans in the back of the case that blow the hot air right out and under my desk (and it gets pretty hot under there. I bought a ceiling fan to cool me off.) I used arctic silver five and now I idle in the high 40s. I should also point out that my previous high-70s was in an HTPC case. My new case probably has something to do with the drop, but the combination of the horizontal orientation of the airflow pointing right at the rear fans is a good combination. Now I see high temps of around 72. The moral of the story: its hot!...which also probably means it consumes a great deal of power.

5 out of 5 eggs

Pros: I have ran some heavy programs on this CPU, and it handles everything with ease. Things like high definition video using Adobe Premiere, Adobe Audition and even games like Doom 3, Half Life 2 and Far Cry all shine with this mega processor. Probably one of the best decisions I have made during my first system build.

Cons: I have to agree, it does run hot, but I am not getting no where near the temp readings some are getting. I am using a Tsunami Dream case with Aspire 500W PSU, which adds some good circulation, and I get idle temps of 45-46C, and max temps after game play and multiple processor driven applications of around 56-58C.

Other Thoughts: I am not much into overclocking CPU's, since this monster does all I need it to. Being my first build, I did notice my BIOS had the core voltage of the CPU much higher than the Intel recommendations. By choosing a lower setting, my system is much more stable and CPU runs at least 10 degress C lower.

Here is my system specs, ALL from newegg.com.

* 2GB Corsair XMS LED Memory
* 250GB Western Digital Sata Hard Drive
* Pentium D Smithfield Duel Core 3.2GHZ
* ATI X800 Series 256MB Video Card
* Asus P5WD2 Premium Motherboard
* Aspire 500W PSU
* Double Layer Sony DVD Burner
* Sony DVD Burner Combo Drive
* Tsunami Dream Case
* Logisys LED keyboard
* Logitech MX Laser 1000 Rechargable Mouse
