H105 on lga 775 motherboard?

grated parmesan · Nov 21, 2016

Is it possible to mount a corsair h105 AIO liquid cooler (or other AIOs) on an lga 775 motherboard? My current cooler is a hyper 212 evo. I am solely looking for solutions to this, please no air cooler suggestions

Rather than suggest an air cooler, I'd like to know what why you're looking at AiO solutions. What CPU are you trying to cool and will you be overclocking?

LGA 775 is not listed as compatible with the H105.

What's the point on 10 year old tech...

Thanks for the reply! I am cooling a q6600 which runs HOT so that's part of the reason I want an AIO, I also just love the overall look of them. They look cleaner than air coolers IMO. But I am ideally looking for at least a 280 mm radiator but a 360 would be nice. I like the look of the h105 and it has a thick radiator, making it comparable to most 280 mm rads. My current case is a Deepcool Dukase v2 but i will be upgrading to the enthoo pro m acrylic (or possibly the eclipse p400s) which has tons of watercooling support.

Okay. You're using a CPU with a 105W TDP that's nearly ten years old. I wouldn't recommend an AiO cooler for most motherboards because it takes the airflow away from the socket. This means that the power delivery systems for the CPU may overheat, causing MOSFET blowouts, sending 12V straight to the CPU and ending with you having a very bad day.

What motherboard do you have just so I have some idea of the general configuration of power delivery systems?

I am running an Intel Extreme Series DX38BT mobo.

That board does not have big enough heatsinks to keep itself cool when the socket will be without airflow.

Please consider an air cooler.

But won't it still receive airflow from the case fans?

Yes, but the air will be pulled across the board instead of being blown against it. This is why Intel stock coolers face their fans downwards.

But that is true for most air coolers. Most don't have their fans facing down, rather across the heatsink of the cooler.

This is also true. You know what else is true? The air flowing out of a fan is not a cylinder, The air spreads out and meets the board as soon as it exits the fan.

The problem with using case fans as MOSFET cooling fans is that they're blowing away from the motherboard. I don't recommend using rear or top mounted fans as intake because you'd be going against the airflow design of most cases.

I have 2 120mm fans as intake in the front of my case. So it will be fine.

I'll look to see if I can find an acceptable quality 240mm AiO cooler that will mount to LGA 775.

Update: Here are all 240mm AiO coolers that fit the LGA 775 socket. The list is sorted by rating high to low.

weberdarren97 :

Thanks mate! Did you happen to find any 280 or 360mm rads that support lga 775?

weberdarren97 · Nov 21, 2016

280mm sorted rating high to low.

360mm sorted rating high to low.

Thanks! This really helped me out!

You're welcome
