I used this guide from Arctic Silver to apply to CPU. 1mm line as shown. Hope I got it right!

Here's pics of my current BIOS setting. OC is off. I'm not sure how to get Turbo Power Limit (Watts) back to (AUTO) so I set it near the default of 95 @ 96.

I decided to stay on the recommended conservative side when OCing & followed this guide Gigabyte Sandy Bridge Overclocking Guide. Doing so uses Intel's Turbo Boost Tech only. There wasn't any other configurations in memory or voltage. The author started @ 4.5Ghz whereas I started @4.0Ghz.

Room temperature is 72 F & core temps in idle are running 37-40C.

I'm not sure what TM1 & TM2 are & not seeing anything in HWiNFO32 to explain. On left is the 1st scan taken while testing new build. On right is now & TM1 & TM2 are red. I'm asking if this means anything?

One difference is I changed the rear case fan & also have tried OC'ing (pic on right is with no OC). Is this a concern?

I have had a quick look at it and it appears to be quite a poor cooler. On the list of approx 50 coolers it was in the bottom 5.

I know from reading certain reviews/comparisons that some coolers can perform worse than the stock cooler on the new sandybridge cpu's.

This could certainly be a possible cause of the high temps , its usually that and voltage to blame anyway.
It isn't a poor cooler.

It does exactly what it is designed to do: provide very low noise levels while cooling about as well or better than the stock retail fan--which has a bad noise profile.

It isn't intended to provide big overclocks.

My system is nearly the same. Stock clock Prime 95 temps with this cooler are about 6 or 8 degrees below the stock Intel cooler (high 60s versus mid 70s). Idle temps are about the same as retail (mid 30s).

The fan on the cooler can be easily replaced with a high RPM 120 mm fan if need be. Any 120 mm fan will fit. That would knock temps down a few degrees, but at the expenses of noise.

If you want cooling performance like a Cooler Master Hyper 212 (for instance), you would have to buy one.

TM stands for thermal monitoring. It should say that when you drag your mouse over TM1 and TM2.

Not sure what the red means. It could mean temps are high right now, or it could mean temps have been high in the past when you overclocked. Mine have always been green.

I doubt if your fan change matters significantly.

The idea of paste isn't to add another layer; rather, it's to fill in the microscopic holes left behind during the lapping process. How much paste you use is going to be determined by the quality of your heatsink; specifically, how well lapped the base is. Personally, I find that's a lot of paste. I use an amount that's almost about the size of a small grain of rice, then I rub it in with rubber gloves... or a handy piece of Saran Wrap. When done, the film of paste left is so thin that it's opaque... remember, it's only for filling holes you can't see.

If your heatsink isn't well lapped, and you can feel grooves on the base, then it's really time to consider another heatsink. The amount of paste you need to compensate for a piss poor lapping really isn't worth it... ends up being counter productive.

The smooth surface of the heatsink was polished & mirror-like. I followed the instructions of the thermal paste manufacture, Arctic Silver. My reference of a 1mm line (see the illustration pic I attached in my earlier post) is also Arctic Silver's description of how much to use. Are you suggesting Arctic Silver's recommendation is wrong?

No, something else altogether.

A poorly lapped base is going to require more paste; thus, Arctic Silver takes this into account. I once had a Thermaltake heatsink/fan assembly that not only sounded like an Apache gunship was in my living room, but the base was so pitted and grooved that it doubled as my wife's pedicure scraper. When she put that bad boy to her heels, the flakes were flyin!

Arctic Silver fudges on the side of caution in order to account for all types of heatsinks... not just the good ones like yours. What they show should work on "any" heatsink. You don't need nearly as much as a crap heatsink.

I think the main issue here is that the idle temps are too high, the cause needs to be determined.

Here is what the idle temps should be.

Scroll down to temperature testing

Overclocking help; your suggestions, please.-i5-2500k-temps-1.png

Idle temps should be around 27C, 37-40C is just too high.

The most common reasons for this, from my searching and experience, is:
1. Loose CPU cooler, be sure it is secure. Easy test is to try to rotate it, should not move easily.
2. Thermal paste application. The general consensus is less is better. Too much paste will increase temps, as will too little but, that is rarely the case.

I applied thermal paste like Fumz mentioned.
My CM Hyper 212+ gives me 27-30C at idle, it is considered a good cooler but, there are much better ones available.

A week ago I was proud of my new PC build accomplishment. Now I'm convinced I didn't get something right. But, I'm glad to have the support of this website. Thanks to all.

When I 1st booted this morning, temps were 30-32C idle. After 30 minutes they're 36-39C idle. I'm going to investigate this soon, but, if the fan isn't seated correctly I need to know what to do & what to do it with.

1st, this fan was tough to install (for me at least, a newbe). It overhangs the MB's #1 RAM slot & crowded #2 slot so badly I had to exchange my original RAM choice to a shorter, heatsink type. That being said, maybe a different fan is in order; one with a more positive mount that leaves no doubt if it's seated. This site has quit a list Top 5 Intel & AMD Heatsinks on Frostytech. No doubt louder but cooler.

If I re-install this fan, I'll need to clean both the CPU & heatsink with rubbing alcohol & what; any type cloth or only microfiber? Paper towel is a no-no?

This time use a rice-size amount of Arctic Silver? Should this be wiped evenly or let the heatsink do that?
