Damn it, I think I screwed up when puting my new heatsink on.

First of all, whether or not fans are difficult to install depends mostly on your case and, at least in my experience, what mounting mechanisms you choose to/are forced to use.

All of the cheap-arsed cases I've owned have pretty much forced me to use screws to mount my fans, though that may be more due to sloth/lack of imagination on my part. There are probably better things to use than screws in a standard fan mount. If you have cheap screws that strip out easily, fan installation is a nightmare. Otherwise it's a breeze even with screws.

As far as intake/exhaust goes, generally you use fans on the front of the case or on the side of the case for intake, while you use fans on the back and/or top for exhaust.

For helping to cool your CPU, there are many different case cooling strategies, though going heavy on exhaust can work (this can interfere with your PSU cooling itself in some cases if you take exhaust fans too far to the extreme). The best strategy is typically to balance intake with exhaust. In other words, try to make sure the total rated cfm of your exhaust fans is about the same as your intake fans. If you do that and negate cable clutter as best as you can, then you should be okay. Personally I like making sure that the net total cfm of my exhaust fans equals or exceeds that of the fan on my HSF, but that's just me.

Also, there used to be a nice cable management sticky in this forum, but I do not know where it has gone. Surely someone here can give you some advice on proper cable management in a CM690.

Finally, before we assume that it is case airflow that is a problem, perhaps you should tell us what intake and exhaust fans you are using now and what case/PSU temps you have as well (something like Speedfan can help you find that information).

If I were you, I'd go with some MX-2, Tuniq TX-2, Shin-Etsu X23, or IC Diamond 7.

The Thermalpaste that came with the Freezer Pro7 is a very good thermal paste.

You will see no significant reduction in temps by using a different thermalpaste!!

I actually got an instant 10C reduction just by cleaning off the pre-applied MX1 and placing a small dollop of MX2 in the center of the CPU. Of course, it may just be that MX2 cures faster than MX1, and that the preapplied TIM seemed to be spread a little thick.

Those are my temps. The only reason it's that low is because my house happens to be cold. The speedfan temps are wrong right? I hear they are usually like 15 degrees lower than what the actual temps are. What should I change?

Some folks have issues with temps in Speedfan reading too low, though that problem has never plagued any of my systems. Must be my "old" hardware.

I'm guessing Temp1 is your CPU and Temp2 is your case/chipset temp? That would be in keeping with the CPU temps you've listed (44C for the CPU), which puts your ambient temps in your case at 41C with the fans cranked up. I think? If 41C is your case temp then that's a little high. Do you have any case or chipset temps listed in your system's BIOS?

In the bios there are 2 temps.

System:31C
CPU:33C

I'm guessing the reason why it's 33C is because I'm only in the bios so it's not doing anything extensive?

I also set cpu smart fan control to disabled so the cpu fan will run 100% I notice like a 3 degree drop.


My motherboard is a P35D also.

Hmm, your BIOS temps should be accurate unless there are known temp reporting issues with your board. What program is giving you temp readings of 45C at idle?

Core Temp

I wasn't sure if I should follow the bios one because when your OS starts won't that take more resources meaning your temps will get higher? I was just thinking that maybe it was that low because I was only in the bios.

Usually you won't see idle times higher in Windows or any other OS than you will idling in the BIOS. Usually. Your temps will rise most when either your CPU and/or GPU are taxed, which should not be the case when sitting idle with your OS fully loaded.

At this point I'm going to assume that your system temp of 31C is at least fairly accurate. That's not too hot, so it doesn't seem like airflow is a big issue here. Your CPU temp isn't very high either, leading me to believe that Speedfan isn't necessarily underreporting temps (or at least, not by very much). Is CoreTemp showing a large difference in temps between the two cores at idle or at load?

I also can't seem to get everest ultimate to show temps. It's not even an option.

I keep saying this, but I'm not for pushing people on a favored bandwagon either.

But diamond TIM outperforms AS5 by 3 or 4C load temperature -- if the particle loading is above 60% [homemade]. IC Diamond is between 90 and 95%.

If you're getting identical temps on each core, then my guess is you aren't suffering from a warped IHS (just a guess, you might want to check anyway when you decide to reseat the HSF).

At this point I'm not sure if I can rationalize why you would be getting such a large difference in detected CPU temp and core temps. Perhaps someone else here can elaborate on that fact?

I have about 4 of those thermometers but from frozencpu and not scythe branded but, trust me, they're identical and they're fairly accurate but, I ended up putting a small pot in each one and calibrating them against an IR laser thermometer I have. They were all within 2C of actual but, that leave a big'ol 4C window if you're using more than one.

There is nothing wrong with your programs or chip. "Core" temperatures are always going to be higher then "CPU" temperatures. These readings are coming from sensors located directly next to each core in the chip. So you're getting a reading before the IHS and your HSF have any chance of dissipating it. The "CPU" readings are from sensors located external to the cores so the heat will have been bled off hence a lower temp.

edit: Everest reports all of these values. My E8400 has coretemps of 43 and a cpu temp of 19-20C when idle. These match up with CoreTemp, Speedfan, and the BIOS values.
