Looking for NB cooling option for either DFI Infinity P965-s or/and ABIT quad GT..

Currently debating if I need to stick with DFI board or just ordered Abit board, and took a look at both board in their diagram from each manuals...

(1) DFI p965-s


(2) ABIT quad GT


Logically I see both boards are similar in terms of their CPU and NB position, so any NB cooling will fit for both IMHO...

Here is the shot of my current board (DFI) installed with HSF (Thermalright)


As you you may notice, pretty good amount of NB head is covered by HSF.. I was just looking around this afternoon, and as long as I'd like to stick with NB cooling has fan on it has 2.5" +/- height... which I doubt it will fit with the HSF..

Any other NB cooling with FAN is available?

Thanks for reading~
 
How do you go about cooling the FETs and southbridge if you replace the northbridge cooler? Individual heatsinks?
 
Thanks everyone for reply.
I have a little glitch to accept the HR-05 though... Since I'd like to keep the current direction of HSF (blow the air towards Back of the case), HR-05 will either be almost touched by HSF or be unable to install... In my Case, PSU is sitting on top, and getting extra FAN on top won't be my favor option...

Here on the one of Reviewer's sites, I can see both HSF and NB cooler sitting alright but no Fan were installed neither of them...

It looks alright but not sure taking off the FAN from HSF for populating another FAN would be wise move...

@ calebb,

Just wonder, what is "FET" stands for?

The FETs (field effect transistors) are the component of the pulse width modulators (which are used to regulate voltages to northbridge/southbridge/CPU/RAM) that generates the most heat. They are actually stable up to very high temperatures, but they draw exponentially more current as their temperature goes up - and if they start drawing more current, it puts more strain on your PSU and can affect CPU voltages...

You also see them referred to as MOSFETs - metal-oxide semiconductor FET.
 
in order to use HR-05 on DFI infinity we have to change the CPU cooler orientation.
cant use vertical ultra-120 extreme with HR-05

i do use them like this

Maybe the HR-05 SLI edition could help?

Great~, Thank you!

@ijozix,
It may fit but not sure. Here is the link I got technical drawing, and I made paper-dummy in 1:1 ratio to measure the gap between NB HSF and vid card. Here is the picture.

Since I took it in quite close distance, picture shows quite distortion, and I'll say this is too close. Then I thought of replacing Vid card to another PCI-E slot. It seems possible. what do you guys think?

@jhartono0002,
Appreciate for reply. Pictures are definitely helpful. Here I was edit them to make sure the air flow on your case..

Is that right? If not can you show me the correct way?
What's temp reading you get from that air flow?

I have this chipset cooler on my F-I90HD and the Thermright Ultra Extreme fits over it. So you can mount the Ultra Extreme in any direction you case/mobo will allow.

@Rokk1972,
I use this for another Mobo (Asus), and I am pretty happy with it. This time, I may wich with fan solution... since I will do OC on the rig plus, 4 sticks of 1GB will be populated, which I expect heavy traffic through the MCH. By the way, I just measure the empty space under the HSF, and it is barely fit those Zalman fanless cooler... at least I got insurance.. Thanks for sharing information~
 
I have to agree with the HR-05. It is the same thing that I am doing with the P5B-delux once I get it. The only thing is that you have to rotate the Ultra-120 so that the fans are horizontal instead of vertical, but if you have an exhaust fan on the top then you shouldn't have any problems and most cases either have a fan on the case or you can use the PSU horizontal fan as the exhaust. Either way they will work very well together and will look very sleek as well.

yes the airflow in the pic correct.
if im not mistaken prolly 1-2'c higher compare to vertical settings.

but i use high CFM SanAce for exhaust,
i do believe low CFM fans will suffers high temp

@kill4killin,
Changing orientation of HSF may not ideal for what I wish to get IMHO... since I do not have exhaust hall on top of my case. Being dependent exhausting major amount of hot air onto PSU seems not the best solution, but I could be wrong.
Thanks for opinion...

@jhartono0002,
I got two no-name brand Fans on Front (intake) and one okayish antec LED fan on back of the case. "Adding higher RPM (and noise...) fans for getting higher CFM" vs. "stick with fanless NB cooler" seem to be deal I may choose from.
 
In my opinion and experience exhausting the heat from the CPU into the PSU has not done any harm nor do I believe it to do any harm to the PSU. It may adversely effect the amount of exhaust you can take out of the case, but at the same time if you have a rear exhaust fan it should compensate for the re-orientation of the CPU fan. I don't see how the HR-05 would fit without re-orienting the CPU cooler regardless though. I could be wrong but the HR-05-SLI might be able to make it so you don't have to adjust the cpu heatsink if you oriented the HR-05-SLI so that instead of it leaning towards the CPU to avoid contact with the graphics card you simply leaned it away from the cpu heatsink to avoid it...it might work but im not sure so you might want a second opinion on that.

@kill4killin,
I'll be happy to settle down if my case can hold 120mm exhaust fan on back of the case, which will increase CFM bit better. I don't think pushing major heat to PSU will cause any damage to PSU as well; just thought it is not the best solution I can take.
With HSF sitting in vertical position (as it is now), HR-05 will not fit.. and here is copy of the picture I posted earlier to show rough measure with paper dummy in real scale of HR-05 SLI..

It still looks alike I need to move the Vid card into lover slot to give enough gap between them.

That large copper block that is sitting ontop of the sata ports (At least the 4 next to the two in my board). If it is, is that a sata cooler? If not, what is it doing? Im very curious.

@Commex,
hmmm, still not so sure which copper blocks on which Mothernoard you are mentioning. Maybe name it or link some reference (including yours) will be helpful.
Thanks.
 
@rybeck
Yea, your right, I don't think that the SLI version will fit either. It will "fit" but I don't think the cooling benefits would be apparent since it is so close to the other components in your case. The only solution that I can see here is either rotate your CPU hs or find another NB cooler that will fit underneath the cooler, much like the stock low profile one but with a fan. Then again you could always just replace the CPU hs with a different one...but thats no good because you have the best cooler on the market already...

Last night, I was about to move the vid card to lower slot, and found "(lower) slot will run @ x4 bandwidth" (compare to x16 bw for top slot).. so Moving the vid card down won't happen, I guess.
Here I found another possibility to increase CFM on my case...
[http://www.newegg.com/product/product.asp?item=N82E16811999141]

Since I don't have nothing sitting on 5.25" bay except one @ very top, the converter will fill the hole perfect.
(1) Front shot

(2) Front shot (closeup)

(3) Holding extra 120mm on the spot where the convert fan will be (it will be further inside though)


Move my HDDs (I got two so far) to the converter (will sit on 5.25" bay), which will clear intake airflow path out @ the bottom...
Then the airflow would be something like this... (*Note: Pink= air from Vertical Fan / Green air from Horizontal Fan)


What do you guys think?
 
that would certainly increase overall airflow through the case, it is actually something I have been considering doing to my own case since I have 3 bays above my CD drive free. Scythe makes a pretty good one if I remember correctly. Another thing you might try is ziptie a fan somewhere near the NB heatsink and see if that does what you want. You might also try taking off the NBHS and applying AS5 or some other high quality thermal paste instead of the crappy pad that they put on it from the factory

After instal it, I'll post some pics..

Should get a fan with 3 pins for RPM reading... and NB cooler. Reading and adjusting "Warning" message from factory S/W due to lack of RPM sensor... :(

Just wanna mention I found another NB coolers

(1) one that I am think of getting... (I may need to take the fan off)

(2) "antec spot cool" fan
