First the specs of the new system.

Case - Antec Nine Hundred
Motherboard - Asus P6T Deluxe V2
CPU - Intel Core i7 920
HSF - Noctua NH-U12P SE1366
Memory - CORSAIR XMS3 6GB (3 x 2GB) TR3X6G1600C8 G
GPU - EVGA 896-P3-1265-AR GeForce GTX 260 Core 216 896MB
PSU - CORSAIR CMPSU-750TX 750W
HD - Western Digital Caviar Black WD1001FALS 1TB
Optical - LITE-ON DVD-ROM DH-16D2S-04
Optical - LITE-ON DVD Burner LH-20A1L-06

Following the instructions on the Arctic Silver I put the arrow in the top left corner and did my best to lay down a small horizontal line across the CPU. I installed the HSF with only one fan pushing air through the fins and out the back of my case. Temps were hovering around 38-40C at idle and were pushing 40-45C during load.

I cleaned both surfaces using ArctiClean. I do not have any lint free cloths but picked up some small microfiber cloths from Office Depot. Wasn't really impressed because I could still see some fibers on the HSF during installation but did my best to get it all.

After doing some reading the following day someone mentioned using coffee filters as a substitute for a lint free cloth. Pulled everything apart and cleaned both surfaces again. But before I cleaned both surfaces I inspected how the grease spread out. It looks like I screwed up somewhere. I'm guessing what I thought was a small bead was still too much?

This time I decided to put a small line of Arctic Silver on the CPU and spread it out with the clean edge of a credit card. I've did this in the past with older CPU's and had good luck with it. During the installation of the HSF I also decided to install the second fan on the Noctua setting it up in a push / pull method and then exhausting out the rear case fan.

Fired the system back up and walked away for a few minutes to let it warm up. ASUS PC Probe II is reporting a solid 40C at idle. GAH!!!

Thoughts? Suggestions? Tips?
 
Are you oc'd at all?

I'm at 37-39 idle with a very very similar setup, but i'm at 3.4ghz.

Not sure that I see anything wrong, but then i'm no expert either. I had odd temp readings intially but was told the paste could need some 'burn in' time in order to achieve maximum efficiency. Another thing was, it was abot 36 hours after that I also locked in some voltages and my temps dropped a good deal.
 
Nope. No overclocking as of yet. I picked up a cleaning cloth for eye glasses at the local Rite Aid today. Going to tear everything apart again either tonight or tomorrow morning and use this cloth to prep both surfaces. Looks to be lint free and hopefully achieve a very clean surface for the AS5.

EDIT - This is my first Intel chip since an old P133. I've been using AMD processors up until this i7. I have no idea if this is considered a normal temp with a case that has as much air flow as an Antec Nine Hundred. My AMD 6000+ X2 was running a solid 32C in this case using a Zalman 9500A.
 
I'm no where near an expert on this by any means, but I just solved my problem with high temps after I realized that my fans were blowing the wrong way. Maybe that will help?
 
What is your ambient temperature? Right now in my room it's probably about 22C. My CPU is idling at 37C. Once I start Prime95 for the stress test, the temp will jump to 60C. But for real world purpose, when I play a games like COD4 or TF2, the temperature hoovers around 45C. I'm using TRUE with one 120mm fan pushing air into the heatsink, as well as recommended portion of arctic silver 5. See this picture.

So I think your temperatures are quite normal. It is the summer, so temps tend to be a bit higher.

I would use the latest version of CoreTemp (0.99.5.20 Beta 64Bit) to monitor CPU temps. If you use a 32Bit OS (unlikely if you are running 6GB of RAM), then use 32Bit CoreTemp.

Also, the two photgraphs that you show of the CPU and HSF with the TIM applied, look okay to me. The TIM has spread throughout the surface of the HSF and CPU IHS.

I've had a look at the product spec for the Noctua NH-U12P SE1366 and it has two fans mounted on it. Two things to look at:

1. Make sure that the fans on the HSF point in the same direction in a push-pull config. i.e. the air flow should look like this: HSF fan 2 <--- HSF <--- HSF fan 1.
Fans usually have directional arrows stamped on the housing to show the direction of rotation and direction of air flow.

2. Make sure that the HSF and rear case fan are orientated correctly so that the air flow looks like this:
Rear case (exhaust) fan <--- HSF fan 2 <--- HSF <--- HSF fan 1
The whole point is that the air passes through the HSF from the front (i.e. HSF fan 1 pushes the air into the HSF and HSF fan 2 pulls the air out of the HSF; hence push-pull config), then the fan in the rear of the case exhausts the hot air from the HSF.

Edit: Btw I use the Arctic Silver 5 single line TIM application method.
 
The ambient temperature in my room is around 23C. I have tripled checked that the fans are in the correct orientation as described by daw123. I pulled everything apart this morning and used the cleaning cloth I picked up yesterday. I felt it did a much better job prepping the surfaces. As I type this my temp of my CPU is 35C as reported by PC Probe II. I'll give the AS5 a chance to heat cycle a few times but I think I got it this time.

daw123 - You are correct. I am running Vista 64. I'll give CoreTemp a look. Vista keeps squawking about PC Probe II on boot about being an unidentified program wanting to access my computer. I haven't had a chance to look into this error yet.
 
I've got an i7 on an EX58-UD4P mounted in a LL V1000B case cooled w/a Noctua NH-U12P as well.
My room ambient is 28c & my temps are running 39-41c...that's with it overclocked to 3.5GHz.
Dunno if that helps you or not.
 
If the temps are bothering you that much, disable the HT and it will cut about 15 -20 ° off it at loads.

But i'm with the others, seems the fans aren't turned right or you aren't getting a good secure fit with the heatsink to the cpu.
