TAT & Speedfan Temps

[Vlip]

Ok, I read a post by someone that seems to really know what they are talking about. They explained the difference between TCase and TJunction, etc. They recommend TAT for stress testing and Speed 4.32 for temp monitoring. I have an E4300 on a Gigabyte mobo with a Scythe Ninja B and two 120mm fans in push-pull configuration. I just read an article here on Anandtech where they were comparing two budget watercooling systems to the top-end air coolers and saw that they were gettiing idle, non-overclocked temperatures of 27C with the Scythe Ninja B and a single Silenx Ixtrema fan.

I would like to know where they get this temperature! I get an idle, stock temperature of 33 C (Core 0) with SpeedFan 4.32 and 51C with TAT! I've also spoken to some one on this forum that has an E4300 running at 3.46GHz and 1.465 VCore and gets 31C idle/69C Load using an Arctic Freezer 7 Pro.

I keep getting scared off from overclocking because I hit 72C with TAT even with mild overclocking. Until I can figure out what my TRUE temperatures are, I cannot proceed with overclocking and have confidence in what I'm doing. By the way, I have been using Artic Silver 5 to install the Sythe Ninja but did not take the mobo out to do so. I've ordered Shin-Etsu and was planning to take the mobo out and re-install the HSF to make sure I get a perfect install this time.

Please, Please help!

Thanks,

In my opinion, when using Speedfan, CoreTemp and TAT the reported temperature is not important. The new on-die sensor reports the delta to the CPU throttling point (which is not known). The utility programs attempt to convert this delta value to a temperature value by subtracting it from the Tjunction. TAT and newer versions of CoreTemp believe the E4300 has a Tjunction of 100C, Speedfan 4.32 assumes 85C. This leads to the different reported values.

The more useful information available is that the E4300 at 72C with TAT is roughly 25-28C away from throttling. Personally, when running the TAT workload test, I don't consider any temperature more than 15C away from throttling to be dangerous because no realworld application comes close to the heat output of TAT.

TAT will also report when the CPU is throttling, so if you actually reach a dangerous temperature point, you'll know.

While that is fine, I still would like to know what my actual temps are. I see postings all over the place where people are stating what temps they get and most overclocking guides I have seen give guidelines of what your temps should be including warnings to say away from anyting over 65C but I can't do any of that if I have no real idea of the real temp. Also, how does someone like Anandtech publish numbers like 27C for idel stock CPU with Scythe Ninja HSF?

There are a lot of different things that can affect your temps. For example if you have good ventilation in your case, or if you have the side door of the case open, or if you set up the damn thing on your desk.
Plus every processor is different.

You can also try the new RivaTuner. It's got a Core2Duo addon which seems to be pretty accurate. At least when you compare it to the bios.

Other than that make sure the cooler is fastened properly, the fans are working, you don't have too much goop(cooling paste) on you processor etc.
Plus Anandtech uses Nvidia's own temp. tool which is a little more forgiving than a lot of other programs.
On my ASUS p5k premium, my q6600 runs just fine at 3.6 79°C prime95 load, while the Asus Probe shows only 66. I have not tried TAT, since it does not work in Vista 64 bit.

Hope it helps..
