780i running hot?

they have a rep for running hot, i believe 70's is ok. Is your system acting funny or are you just concerned?If possible (not sure about this board) remove hsf clean the chip throw on some thermal compound and reseat that puppy. Also are you going by what the bios reads?
 
im running an evga 780i and it hits 78c i was really amazed cause i just came from having a 680i i have a p03 bios and it says the same as speed fan.heatsink is clean as a whistle
 
are your voltages good? check these links it seems common man. This is why im most likely going x48 on my next build. I would like sli, but i dont know how much faith i have in nvid chipsets and the only intel / sli solution is skulltrail and you can kill that noise right now cause i dont have that kind of bread. Good luck man. Peace

RUN, don't walk away from the 780i. Nvidia has to make a better more stable setup or I'm never going to be able to enjoy SLI 😉 I had the Striker II Formula and it never worked properly. Overheating like crazy on stock settings...Manually done ofc. It's been RMA'ed away...


I have great hopes for 790i, given that Anandtech doesn't give a short look and then no review like they did with the Formula.

'Running hot' is a gross understatement. These things scream "Paris is burning". :laugh:

It gets worse with quad-cores. Active cooling is a MUST.
 
Your evga reference board should not be running above 70c. In many cases, when a reference (evga & xfx) 680i NB topped 70c, it was an indication that the board was close to death. You should dismantle your computer and ensure the following:

1. That your heat sinks are making proper contact with the components. Many times a board will leave the factory w/o the heatsinks being fitted properly. Check the NB, SB, bridge chip, and mosfets.

2. That the TIM is applied correctly - i.e. there isn't too much or too little. This is a common issue with evga and XFX boards. Many times too much TIM will be applied between the heat sink and the component, which causes excess heat. If you find that the TIM isn't applied well, you can replace it. Be sure to use a non-conductive TIM such as Arctic Silver Ceramique. AS5 is slightly conductive and can be dangerous when used on chipset components -- especially the mosfets.

nVidia chipsets do run hot, but they really aren't supposed to run that hot, especially if you plan to OC. If you can get it down so that it runs in the 50s, then you're set. Otherwise, you might want to invest in some 3rd party cooling.
 
The 780I on my MSI P7N DIAMOND runs in the high 50s and that when OC'ing nd raisiing the NB voltage to 1.4. So I don't think 70s is normal. Under normal voltage I'm in the 40s under load.
 
I have the same results with my P7N Diamond. I do believe that MSI has found the trick to a cooler running NB. Even so, I still added an Antec Spot Cool for some active cooling.
 
yeah i have the chipset fan and everything it idles at 68 and goes to 75 its pretty wack. but u see since this post i just got a newboard cause the other evga was having tech problems so they sent me a new one and still same temps pretty rediucluous if u ask me and i have about 3 intake and 2 outake 120mm's with ecellent path flow
 
I've read this occurs because of poor TIM application when the heatsinks are applied at the factory. Many people, myself included, solved their high NB temps by removing the stock heatsink and reapplying the TIM on the NB and SB.

Vist the forums at www.evga.com and there are some great posts that explain how to easily fix this problem. For me I just removed the screws holding the heatsink to the motherboard, cleaned the chips off, and then reapplied some AS MX-2.

In all fairness the Striker II is not a reference design so blame Asus before you point the finger at Nvidia. My experience with the 780i chipset has been fantastic. 1st board I've ever owned that has given me exactly zero problems that I didn't create for myself by tinkering with the bios.
 
AS5 is slightly conductive and could easily short out your motherboard if even a tiny bit makes contact with the underlying PCB. Remember that motherboard components don't have heat spreaders, unlike the processor.

If AS5 is applied such that there is no chance the grease will spread out from the chip, then there shouldn't be a problem. If you are going to use AS5, I would avoid using it on the mosfets. These are particularly sensitive, and the area for safe application is quite small. Note that you should be able to find Ceramique at any Radioshack.
 
I haven't looked at the vid since I'm at work but I have the EVGA 780i and initially I had MCP temps in the 80C range!

This all comes down to poor QA on the board, it just wasn't attached properly. I took apart the heatpipe assembly, I scraped the bottom clean, applied AS, and put it back on the board. I run this board at 2000-2100 (500-525MHz) and my temps with the MCP voltage maxed out at 1.75v is 55C!
