Thats a bodge and a half. 
My son has a closed loop liquid cooler (pre assembled) and it removes all heat straight out of the back. But he does have 2 intake fans and two exhausts in the top, but it is a gaming machine. A larger copper cooler might be better. I have a Zalman 'flower' type cooler o out older PC.

[QUOTE 4472251, member: 9609"]it shouldn't be if the chip is pumping out the same amount of heat.

If the cooling is more effective while the same heat is produced more of it is transferred to ambient air hence cupboard hotter and cpu cooler

Also if it will fit or you're running case open. You won't get much better air cooling than with a hyper ego 212 for around £30

All those sockets on a wooden surface, in an enclosed space (a very hot space now!) are a fire hazard, that set up is against the current electrical safety regulations.
I know that because I recently had my flat inspected

[QUOTE 4472542, member: 9609"]the mass of the cpu is very small the overall temp of the cupboard would be the same whatever rate the cooling was.[/QUOTE]
So where does the heat go? It can't disappear.

[QUOTE 4470138, member: 9609"] I downloaded a temperature monitor for the CPU and was quite amazed that when under load the CPU is running at about 90c and is peaking at 125c [/QUOTE]
[QUOTE 4470138, member: 9609"](under normal usage the cupboard is at about 25c and the CPU will be 45 -65 peaking at 85c[/QUOTE]
Thar's more like it.
This might not be what you want to hear if the budget is limited but I think you are probably approaching this from the wrong end. You are trying to fix an overheating cpu by increasing the cooling when you should be looking at reducing the load so it doesn't get anywhere near 125c in the first place.
I'm no pc wizard but I'd hazard a guess that you are running the risk of frying your cpu if it's that hot, in fact I'm kind of surprised it hasn't safety cut out already.
I'd say you need at the least a discrete graphics card (as mentioned upthread). If you know anyone with a pc that has a gfx card you might try it on theirs and check the temps to get an idea?
I had a quick look for a minimum cpu/gfx combo for that application but found nothing useful with a brief search, you might improve on that with a longer google.....

You have to keep the Junction temperature at less than 125C if you are to avoid failure. The Junction temperature is the actual internal guts of the CPU where the electrons are doing their stuff. Here's an article. Look at Figure 1 bottom right.

[QUOTE 4472725, member: 9609"]exactly, cooling the cpu quicker will not make the overall temperature within the cupboard greater, the only way to do that would be generate more heat[/QUOTE]
the only way to cool the system is to radiate it to the ambient air. The more heat you can radiate away the hotter the ambient temperature will become up to a limit.
Just like your fridge blows out hot air. Stick that in your cupboard and it will soon get very hot unless you can get the heat out of the cupboard.
My water cooled system raised the room temperature by 8degrees under heavy sustained load. Stick it in a confined space and it will become even more prominent.
