Temps too high?

[firebug88]

With my water cooling rig, i am currently sitting at 42-45 idle and 54-56 load for my AMD 940 CPU. I have a Swiftech waterblock, a DD Black Ice Stealth 240, Swiftech MCP655-B pump, and large reservoir. I think i should be getting better temps than this. I dont know if my fans arent pulling enough through the radiator or maybe the radiator is just too small.

Here is an old pic of my system - loop is still the same but have upgraded a few of the components.

Let me know what you think.

are you fans in push or pull? Try remounting the WB?

Agree your temps look high, unless your ambient temps are very high.

I think you meant "radiator" instead of "reservoir" wrt the fans pulling air through. Can't tell how much clearance you have on the bottom of your case, but are you pulling fresh air into the case through your radiator?

Also, what CFM / RPM are your fans running. I'd make sure everything is clean (no dust build up), remount your blocks, and adjust your fans (or try different ones) before changing anything else out.

The fans are pulling air through the radiator at around 800-1200 rpm (have them set low but even if i put them on high i dont get but 1-2 degree diff). Also, i just finished remounting the waterblock, reapplying the thermal paste, and cleaning out the dust and temps are the same. I dont have much clearance room at the bottom for air to come though but it should be enough i think.

Could try flipping the fans, put them on the bottom then then the rad. Basically still pulling in cooler air, but pushing the air through the radiator.

I m going to try to a different arrangement this weekend. I want to put the radiator somewhere else but i didnt have another spot (unless i just overlooked it).

You could try lofting the case to improve airflow/clearance and see if the temps go down. Otherwise, I'd say you need fans with higher CFM.

Just bought some new fans.

Hope they do a better job. Will update temps when i get them in.

ok so i installed one of the new fans (the other wont fit at the moment) and my temps have went down to 38-40 idle. Will install the other soon, but i have to change a few things around to get clearance.

You "upgraded" to SilentX? Looks like someone got ripped ~.~

Anyway, if you noticed lower temps with stronger fans [I assume the ambient temp was the same, right? Also, give us some LOAD temps, they're what matter] it means the radiator is bottlenecking your cooling -> get a bigger one/add another - FIXED

What do you mean by ripped? They are very quite and i can feel alot more air coming from them.

I just ordered another radiator - forget the name but it is twice as thick and is a two pass radiator.

 

[firebug88]

After i installed the new fans and radiator, my temps went down to 38 idle and about 47-49 on load. Plus i overclocked it to 3.5 so far. The old temps were on stock speed.

I'm in the blue camp but those temps look phenomenal to me! Especially the 9-11 degree increase from idle to load. My Ci7 920 at 3.6GHz 1.325 Vcore jumps around 25 degrees under full load...
