I put my finger on the heatsink that is highlighted (think it's the northbridge??) and it is too hot to touch. I did have a bad stick of RAM a few days ago (the RAM got extremely hot) but I swapped it out with some good RAM and it runs warm now.

Anyway that heatsink is smoking hot, is it normal? I'm not doing any overclocking right now, everything is at stock settings.

Thank You!

When is it smoking hot? 5 Minutes after you start the pc or after an hour of gaming / benchmarking? Without a fan I'm sure that little guy is going to get hot, but it may also make a difference what type of CPU cooler and airflow you have in the case.

You are correct, it is the northbridge.

15 Minutes after I turn it on it's very hot without playing any games. There is no fan on it or in the case, I am getting two fans Sunday, one to push & one to pull air out of the case. I do have the side of the case open to let more air circulation.

I have a stock CPU cooler with my E6300.

Here is a photo of my computer they way it is setup right now

That is exactly what I pictured. I read through some of the reivews on newegg for that board and there are a few other people saying the same thing. It sounds like it will get a little hot which is unsuprising considering it doesn't have a fan. The biggest problem that you have right now is there is no airflow in the case so both your graphics card and your CPU pump heat into case which causes the northbridge to get hotter than normal.

The way the stock intel cooler works it is basically pushing hot air off the the cpu directly onto the northbridge as well. Once you get your fans I would put the cover back on, run it for a little while and then check it again. The airflow should make a huge difference.

If you boot into your bios goto the power tab, and then hardware monitoring. Under the CPU temperature should be something called "MB temperature". That will list the exact temp for the northbridge. In their little screenshot they show it at 41C which I'm going to guess is probably a normal temp for it. If yours is going over say 65C then it is probably running too hot. I'm not exactly sure what kind of temps that chipset runs, but I'm just making my best guess going off of their screenshot.

The front a rear fans should make quite a difference as there will be much better airflow. What I would do is to makesure all the cables are neat and tidy(zip ties etc), to allow the air from the front to pass over the NB heat sink. I would try to get their ide cable way out of the way or mod it to make it round or use a round one if possible (I am glad I don't have to deal with IDE cable anymore).

Thanks guys! Ill stop freaking out about it now lol. My house temp is about 70f but during the summer it can get to 80f so I'm glad I noticed it now. I will do some wire management like you said.

Because of the orientation of the fins on the northbridge sink it will be hard to get good airflow on the important middle fins unless you use a side panel fan or 3rd party northbridge cooler,
I can see how the T fin would catch some air but 3rd party is better as your ram will block good flow.

I use Akasa Cool Blue AK-210's (North and Southbridges) with arctic alumina epoxy but like I said before the Zalman is very good if you have the good flow

I don't think I will have anymore electrical connection for fans after I put the two new fans in it? But I'm a noob so who knows lol.

Will this work with my motherbored? I only have a 300w power supply, how much power do these fans suck up?

I use this.

With no fan in my Antec 900, it stays cool to the touch. Very easy to install also, but you will have to remove the motherboard.

Fans are usually rated at about 2W without lights, and 3W with lighting. A smaller fan like that is probably closer to 1W. Most fans come with a 3 pin to 4 pin molex adapter, and these can be chained together. http://www.newegg.com/Product/Product.aspx?Item=N82E16812189119

Normally I leave one of my power connectors for just fans and plug a few fans into that connector and nothing else. I have had problems in the past with those little fan connectors stop working and causing issues with devices that were also plugged into the same place.

I don't think you'll have to worry too much about a couple of extra fans. For now I would just get the case fans in there and then see what kind of temperatures it is running. I'm not a big fan of those little 40mm fans because they are all loud and annoying. If you can get by without a fan it would be better IMO. I think that heatsink is actually tall enough it should be able to catch some air.

Mind saying what the product is grey_1? I have a little beef with performance pcs after their horrible service so I refuse to even visit their website let alone buy anything from them again.

$24.95, or less depending where you buy from.

If my temps are being read right, 52c @ load prior, 37c max with this.

As yes, I was thinking about getting one of those guys before, but there was no way it would work on a DFI Lanparty Expert. I wonder if it fits on a 780i...

I have 2x40mm Akasa blue fans running and don't hear a peep from them on full with everything else turned down,
only if I put my ear up close to them, then I can hear something.

How do you mount your 40mms for that? I've used Zalman NB heatsinks before, they're fantastic, but adding any extra cooling if desired looks tough.

I was making a side comment about loud 40mm fans ,I dont use a Zalman NB cooler as it was easier for me to just stick fans on.
I add quote now.

You gota be kidding me! i had 1 of those fans on my ABIT IN9 and i coul hear it. Your case must be loud!

My case is very quiet ,There wasnt a peep from my so called "loud" raptors either.

The fans are both on a controller though which lessens the speed even at full.
