Looking for the best possible HSF for E8400 OC

I have an Antec P180 case; AUSU P5Q-E Motherboard; 8GB Corsaire 1066; 7 x 500GB SATAII 7200RPM drives, Nvidia 260GTX OC, Creative soundcard, DVD-R, CD-R.

I plan to overclock this to maybe 4.0GHz or as close as I can get without going crazy on voltage.

I got a Vendetta2, that I have yet to unpack and the Proc came with the stok intel cooler...

I'm thinking I'll start with the stock cooler, but I want to make sure I have the best cooling solution before I take it out of the box.

thanks for the help.
 
S1284 is vastly inferior to S1283 since the additional heatpipe actually reduces the footprint on the CPU heat spreader S1284 heatpipe issue

I would consider Tuniq Tower 120, Thermalright Ultra 120 or Thermalright Ultra 120 eXtreme or the S1283.
 
I wasn't aware of the info on the S1284. Thanks for clarifying that!
I've got a Tuniq Tower as well. It & the S1283 i'm currently running perform about the same.
 
The Vendetta 2 should perform as well as a TR U-120 Extreme. On the other direct-touch models, some reviews I've read are inconclusive or the data is counter to multiple other reviews and known performance results.

The best heatpipe coolers should also turn up in review measurements of thermal resistance. And I do not believe that the lowest among heatpipe coolers (lower is better) -- is much lower than 0.085+ C/W. The TRUE thermal resistance minimum may be somewhere around 0.093 C/W. The overall thermal resistance for the IFX-14 (ThermalRight) is probably a tad lower than that.
 
Whatever you decide, go ahead and install the cooler when you do the build, you'll probably have to remove the board to do it anyway and why wait?
 
OK, so I guess I'll stick with the Vendetta 2.

Does anyone know if there is a bolt through kit for this? It has the pin thing, but I've heard it's better to get the bolt through type.

thanks
 
Careful - I'm not sure that the bolt-thru kits works with the Vendetta 2. I recall someone (Rubycon?) mentioning that it doesn't, because the heatsink fin "footprint" overlaps the location of the bolt holes. With the Xigmatek, it works fine because the fins don't overhang the bolts.
 
You know, I think I'll just return the Vendetta to the store. It's not what I really wanted anyway.

So now, I have to choose a new cooler. Maybe the TR120.
 
Thermalright has QC issues with their base and refuse to admit that it's a manufacturing flaw. You have been warned. 😛
 
I ended up getting the Noctua NH-U12P. It was expensive, but I just didn't want to mess around anymore. I hear that this is a pretty decent cooler...yes?
 
Well . . . I hope insightful folks take heed of my post here, after Cr0nj0b solved his problem.

You never get the full understanding without doing it the hard way: buying the cooler and testing it.

I had decided to try the OCZ Vendetta 2 with an E8400 rig -- twin to my 680i setup for last year.

Forums suggested that I install at least the BIOS version 1305 -- released about three months before the E8400 became generally available from Intel. The system would post a message: "Upgrade BIOS to unlock full features of this new processor." Despite user troubles with flashing the last BIOS release version 1504, I had a "pre-flashed" PLCC BIOS chip to plug in, and everything is fine.

However, the 1305 BIOS gave me an (obviously) erroneous reading of the CPU tCase temperature -- showing 10C at idle. With the newest BIOS, the hardware monitor screen shows 50 to 51C. Keep in mind my room ambient was in the high 70's Fahrenheit when this reading was taken.

I can SEE where the black pushpins on the OCZ cooler are locked in as far as they go through the motherboard -- all four of them. I used diamond paste.

Reseating the cooler is such a chore, I'm inclined to simply remove it and replace it with another.

So -- my concerns:

If there was an error in reading tCase under the earlier BIOS, how can I be sure that the high value shown under the new BIOS is accurate?

If it IS accurate, how could this OCZ Vend 2 show such a high temperature at idle? I'M the one always going around telling people to check their heatsink mountings, but I DID! And it all looks Kosher! I cannot see any reason why the BIOS temperature value would be 50C at idle.

EDIT: I don't think the word is in yet on why my E8400 shows BIOS CPU at 50C idle (room = approx 78F) with the OCZ Vend 2. I've so far set it up so that all airflow through the cooler is provided by the rear exhaust 120x38 Panaflo -- there is no pusher fan installed. I should probably try the pusher-fan mounted to the cooler, as this was the combination I used in a twin machine built last year (twin for the electronics only). I don't want to give the OCZ Vend 2 any undeserved bad press, and there are indications from reviews of other coolers that the highest temperatures can result from some puller-fan configurations. Anyone interested -- I'll let you know on this thread.
