HS Direction

[Buggedout]

Is there any benefit of having the HS attached with the fans blowing from right to left as apposed to having the fans blowing upwards?

From the random pic's I have seen about 90% of people opt for a right to left flow and only about 10% of people going for the upwards flow.

I currently have a 120mm exhaust on the rear and a 200mm exhaust on the top. Would I therefore be better to have the HS heat directed at the larger fan?

You are probably best having the Heatsink aimed horizontally. The 200mm exhaust fan is good to have, but I guess you have a big, hot GPU just below the heatsink - which isn't ideal for high airflow, low temp intake airflow.

However, I believe there is a benefit having an i7 heatsink orientated vertically - as the the way the cores are orientated this means more heatpipes are directly above the cores. However, this effect is pretty small (especially as the IHS reduces this) and the above factors will generally negate any benefit.

Infact there is quite a lot of space between the GPU and HS. Im quite sure the GPU would be unaffected.

Here's a pic showing the directional airflow, but is doesn't indicate whether rear or top exhaust would be better suited.

Some set ups, mainly amd iirc, you have no option but to mount the cpu heatsink with the airflow vertically, with a top mount fan it probably makes negligable difference tbh. Without a top mount fan it might cause a degree or two increase of internal temps (guessing).
